00:00:00 Many airports have carpets in their boarding areas.

00:00:03 This little element of comfort is usually accompanied by a few others.

00:00:07 Lower ceilings, comfortable seats and pleasant natural lighting.

00:00:12 All this costs more at airports and carpets are not as easy to clean as hard floors.

00:00:17 But it creates a pleasant sensation for passengers who are waiting for their flight,

00:00:22 which makes them more relaxed.

00:00:23 However, it is not just a gesture of goodwill from the airports.

00:00:28 According to behavioral research,

00:00:30 calm passengers are 7 to 10% more likely to go shopping

00:00:34 and actually buy something in the duty-free zone.

00:00:38 So by investing in the passengers' comfort,

00:00:40 airports actually increase their income.

00:00:43 If you have always wanted to know what happens to your luggage when you are on board the plane,

00:00:47 the short answer is that the airport staff does not know it once it has left its territory

00:00:52 and that it probably does not care.

00:00:54 Sorry to tell you.

00:00:56 Scanners read the barcode and automatically sort your luggage according to their destination.

00:01:01 The three main tasks of airport luggage carriers

00:01:04 are to move bags from the registration area to the boarding door,

00:01:08 to move them from one door to the other when you have a correspondence,

00:01:11 and to move them from the plane to the baggage collection area.

00:01:15 And that's all.

00:01:16 So if your luggage does not move fast enough,

00:01:19 they may be late for your correspondence flight.

00:01:22 Or vice versa, your luggage can arrive at your destination before you

00:01:26 because you are stuck at passport control.

00:01:28 Another problem can arise if you forget to remove an old label indicating a different destination.

00:01:33 In this case, the scanner could send your luggage to the wrong country.

00:01:37 Most airports are equipped with giant kitchens

00:01:40 where meals are made for passengers.

00:01:43 These kitchens generally prepare food for different airlines at the same time.

00:01:48 And since this plane food, if tasty, must be cooked about 6 to 10 hours in advance,

00:01:53 the kitchens work 24 hours a day, 7 days a week.

00:01:57 And as surprising as it may seem,

00:01:59 the menu of your flight is prepared up to a year in advance.

00:02:03 This is a common practice for most airlines

00:02:06 because each ingredient counts and increases expenses.

00:02:09 By the way, it's interesting,

00:02:10 an airline managed to save $40,000

00:02:14 after removing a single olive from each salad they served on its flights.

00:02:18 Airport staff sometimes ask passengers to rub their hands on a piece of fabric

00:02:23 before putting it in a special machine.

00:02:25 It may seem strange, but it's totally harmless.

00:02:28 It's simply a routine check carried out by a machine called an atomizer

00:02:34 before their working day begins.

00:02:36 Employees put samples of dangerous chemical products in the machine.

00:02:40 The machine memorizes its odors

00:02:42 and in case a person's hands exhale these chemicals,

00:02:45 it alerts the airport staff.

00:02:47 You've probably experienced this before.

00:02:50 You arrive at the security check and suddenly,

00:02:52 it turns out you have something forbidden in your hand luggage.

00:02:55 But don't worry, all objects taken during the inspection before the flight

00:02:59 can be kept at the airport for up to 3 months.

00:03:02 In addition, you can have them sent by mail to any address.

00:03:07 Security-taken items that have not been claimed

00:03:11 can also be sold during special auction sales

00:03:14 and are delivered around the world.

00:03:16 If you have a long stopover between two flights,

00:03:18 going to the closest hotel to rest

00:03:21 may not be the cheapest option.

00:03:23 There's a much better tip.

00:03:25 Check if the airport or airline

00:03:27 sells a 24/7 VIP access to the VIP lounge.

00:03:31 In most cases, you can find free snacks and drinks

00:03:35 and use free shower and lounge cabins at a very affordable price.

00:03:39 In airports with several terminals,

00:03:41 look for underground passages connecting terminals

00:03:44 that most people may not know about.

00:03:46 For example, at Frankfurt airport in Germany,

00:03:49 there is a pedestrian tunnel between terminal 1 and terminal 2

00:03:53 that is mostly used by employees

00:03:56 because passengers are simply not aware of its existence.

00:03:59 There is a term for the 60 minutes that follow the end of the recording.

00:04:03 The golden hour.

00:04:04 This is the time when passengers spend the most money

00:04:08 in stores and out-of-tax areas of the airport.

00:04:11 And placing the most comfortable seats

00:04:14 in these areas right in front of the stores

00:04:16 is another tip to attract you to go shopping.

00:04:19 Let's face it, sitting in a comfortable chair

00:04:22 while looking at a window or a window can be tempting.

00:04:25 And that's exactly what airports want you to feel.

00:04:28 If your flight is overbooked

00:04:29 and you can't take the plane on time,

00:04:31 don't rush to accept the first gift

00:04:34 they offer you as a compensation.

00:04:36 Normally, airline companies

00:04:38 have to go through the auctions until they have enough volunteers

00:04:41 to give up their seats.

00:04:43 And if they don't do so

00:04:44 and you were refused involuntarily,

00:04:46 you can insist on getting a refund instead.

00:04:50 Depending on the price of your ticket and the time of your delay,

00:04:53 you could have a right to a fee of up to 1,300 euros.

00:04:57 Most airports hire experts called "profileurs".

00:05:01 These people practice what is called "la spot"

00:05:04 or passenger inspection technique.

00:05:06 By observation, they carefully analyze facial expressions,

00:05:09 gestures and behavior to detect suspicious people.

00:05:13 Their job is to notice signs and long anxiety verbs

00:05:16 like people biting their lips,

00:05:18 eating or looking around them.

00:05:21 If a profileur notices that a person is behaving strangely,

00:05:24 he can invite him to a more in-depth inspection

00:05:26 during which he will question him to try to find out more about him.

00:05:30 Profileurs work both in the main halls

00:05:33 and at passport control.

00:05:34 The typical question they ask is

00:05:36 "What is the purpose of your visit?"

00:05:38 They then check the reaction of the person to this question.

00:05:41 No matter how reserved a passenger is,

00:05:43 if he has something to hide,

00:05:44 agents will discover it

00:05:46 thanks to the smallest clues in his attitude.

00:05:48 Before your luggage even gets on the plane,

00:05:51 they go through five levels of security.

00:05:53 And one of them, in addition to scanning the content,

00:05:56 takes control of a dog capable of sniffing dangerous chemical products.

00:06:00 It's well known that a dog's nose is much more powerful

00:06:03 than that of any human.

00:06:04 In fact, dogs can distinguish smells

00:06:06 from 10,000 to 100,000 times better than humans.

00:06:08 No wonder airports take advantage of this super sense for safety

00:06:13 and regularly use these sniffing dogs

00:06:15 to detect suspicious substances.

00:06:17 In addition, you won't even be able to distinguish

00:06:19 a detection dog from a normal dog.

00:06:21 Unlike police dogs,

00:06:23 those who work in airports

00:06:24 are not trained to frighten or intimidate people.

00:06:27 The most popular sniffing breeds

00:06:29 are the Goldel Retriever,

00:06:31 Labrador and German Brach.

00:06:33 Charging your phone to a specially designated place

00:06:35 may seem practical,

00:06:36 but it's not necessarily safe.

00:06:38 If the charging station only allows you to plug your cord into USB,

00:06:42 you risk having a malicious software installed on your phone

00:06:45 without you noticing.

00:06:47 The only safe way to charge your phone or tablet

00:06:50 is to find a wall outlet

00:06:52 and use it with your own charger.

00:06:54 The same goes for free WiFi at airports.

00:06:57 Apart from the fact that airports are more likely to ask you to authenticate,

00:07:01 someone can easily access your data

00:07:03 when you use a non-protected hotspot.

00:07:06 It's safer to use your mobile data,

00:07:08 but if you absolutely have to use the airport's WiFi,

00:07:11 delete or encrypt all important information on your device.

00:07:15 It can be exhausting to have to take out your laptop

00:07:18 from your suitcase each time for security checks,

00:07:21 but the airport staff

00:07:23 need to see your device

00:07:24 to make sure nothing is hidden inside.

00:07:26 On the screen of a X-ray scanner,

00:07:28 a laptop looks like a semi-transparent object.

00:07:31 It has a hard drive, a CD player

00:07:33 and other clearly visible components.

00:07:35 But security staff can't see

00:07:37 what's behind some of these pieces.

00:07:39 For example, a dense and rather bulky battery.

00:07:42 People tend to choose the nearest security line to them.

00:07:46 If this line turns out to be crowded,

00:07:47 just look around you

00:07:49 after checking your ID and tickets.

00:07:51 You may see another checkpoint with far fewer people.

00:07:55 Some checkpoints at airports

00:07:56 are located at the border of the terminal

00:07:59 and passengers don't notice them.

00:08:01 Making a security check

00:08:03 can save you a lot of time

00:08:04 when travelling inside and outside the US.

00:08:07 Being a member of this programme

00:08:09 has many advantages.

00:08:10 First of all, security check and passport control

00:08:13 are much faster.

00:08:14 If you've opted for security check,

00:08:16 you won't have to take off your shoes,

00:08:18 remove your seatbelt or place objects

00:08:20 like liquids and your laptop

00:08:22 in special bins.

00:08:23 If you don't take the plane from or to the US,

00:08:26 you can look for similar services available in your country.

00:08:30 If you're travelling in economy class

00:08:32 but you don't like it...

00:08:33 Who likes it?

00:08:34 Register online

00:08:35 and check the seat options

00:08:37 about four days before your flight.

00:08:38 That's when airlines

00:08:41 start to overclass seats

00:08:43 and you can get a free or even free overclassing

00:08:46 in business class.

00:08:48 You can also request an overclassing

00:08:51 when you're already at the airport.

00:08:53 Most people forget this possibility

00:08:55 or just make fun of it.

00:08:56 So, try your luck!

00:08:59 Taking the plane has become a routine for many people.

00:09:03 But even the greatest travellers

00:09:05 sometimes don't know what to do

00:09:07 on a plane.

00:09:09 And to start with,

00:09:10 you never set foot on the ground.

00:09:11 It's one of the golden rules of travelling by plane.

00:09:14 Not to mention the unpleasant odours,

00:09:17 the ground on the plane is very dirty.

00:09:21 People who suffer from contagious foot problems

00:09:23 may have walked barefoot in the aviatory aisles.

00:09:26 And it's very likely that there's a lot of dirt

00:09:28 left by the previous passengers.

00:09:30 And we're not even talking about the ground of the toilets.

00:09:34 If your feet need a bit of freedom,

00:09:36 take off your shoes.

00:09:37 But at least keep your socks on.

00:09:39 Or wear a pair of light slippers.

00:09:42 Don't forget that the air pressurised in the cabin

00:09:44 is as dry as that of the Sahara desert,

00:09:47 with only 20% humidity.

00:09:51 That's why you may feel a certain discomfort

00:09:53 in the skin after a flight.

00:09:55 Wouldn't it be more justifiable

00:09:56 to install air humidifiers in the cabin?

00:10:00 In fact, the extra weight would cost too much money

00:10:02 to airlines.

00:10:04 In addition, the aircraft's hull

00:10:05 is mainly made of aluminium and other metals.

00:10:08 And the humid air could cause corrosion.

00:10:11 So don't forget to bring a moisturizing cream

00:10:12 and use it during the flight.

00:10:15 Always put your tablet back up

00:10:16 as soon as the plane starts moving on the tarmac.

00:10:19 And never lower it

00:10:20 during take-off and landing.

00:10:22 It's a safety measure

00:10:23 that guarantees that you and the other passengers

00:10:25 will have a clear passage

00:10:27 in case of an emergency evacuation.

00:10:29 In the same order of ideas,

00:10:31 keep your seat upright

00:10:32 during take-off and landing.

00:10:34 First of all, a leaning seat

00:10:36 can seriously slow down an emergency evacuation

00:10:38 because it blocks the person sitting behind.

00:10:41 Then, the more you lean backwards,

00:10:44 the more difficult it is to get into a safe position

00:10:46 during an emergency landing.

00:10:49 Try to avoid sleeping during

00:10:51 or just after take-off and landing.

00:10:53 First of all, it's not good for your health.

00:10:56 The main problem is that the air pressure

00:10:58 inside the cabin changes very quickly

00:11:00 during these flight phases.

00:11:02 And this affects the air pressure in your ears.

00:11:06 So it's important to be vigilant during these phases,

00:11:09 to relax and clear your ears,

00:11:11 for example by barking or swallowing frequently.

00:11:14 Chewing gum also works.

00:11:15 If you sleep, you can't do it,

00:11:17 which can lead to permanent damage.

00:11:20 And of course, there's the issue of safety.

00:11:22 Most accidents occur during take-off and landing.

00:11:26 If you sleep during these phases,

00:11:27 you risk not being alert enough in case of an emergency.

00:11:31 The following recommendation

00:11:33 comes from the Environment Protection Agency.

00:11:37 According to them, it's better not to drink hot drinks on the plane.

00:11:42 The water used to make tea and coffee

00:11:44 doesn't come from bottles.

00:11:45 It's tap water.

00:11:47 But the plane's water tanks are often old

00:11:49 and full of bacteria.

00:11:51 In 2004, a study revealed that more than 12%

00:11:53 of water samples contained harmful bacteria.

00:11:58 If you decide to drink a hot drink on the plane,

00:12:01 never pour yourself coffee or tea.

00:12:04 The flight staff is trained at this age

00:12:06 in the crowded aisles of a moving plane.

00:12:08 This will prevent you from getting burned

00:12:11 or other passengers from getting burned.

00:12:13 It's better not to order Coca-Cola on a plane.

00:12:16 The pressure in the cabin causes a lot of foam.

00:12:19 For obvious reasons,

00:12:21 the flight staff doesn't want to serve you a foam-filled cup.

00:12:24 That's why they only fill half of the cup.

00:12:27 They wait for the foam to fall,

00:12:29 then they finish pouring it.

00:12:31 It can take a long time.

00:12:33 Keep your air conditioner open.

00:12:35 This will reduce the spread of germs.

00:12:37 The planes are equipped with high-quality air filters.

00:12:40 They retain up to 99% of the germs in the air.

00:12:44 So you have nothing to worry about.

00:12:46 But don't forget to wipe your tablet.

00:12:48 With eight times more bacteria

00:12:49 than the toilet flush button,

00:12:51 it's the dirtiest place on board.

00:12:54 Another thing to avoid is to put your head on the window

00:12:57 if you have a seat next to the window.

00:12:58 You don't know who occupied your seat before you,

00:13:01 and the window may be covered with germs anyway.

00:13:06 Avoid wearing flip-flops or high heels during a flight.

00:13:11 Your survival could be at stake.

00:13:13 Indeed, these two types of shoes

00:13:15 make it very difficult to evacuate quickly from the plane.

00:13:20 If you wear high heels,

00:13:21 you will have to leave them behind anyway

00:13:23 in case the crew uses emergency flip-flops

00:13:26 during an evacuation.

00:13:28 The heels may damage the flip-flops,

00:13:31 and you will have to remove them.

00:13:32 Now, ask yourself if you really want to get out of the plane barefoot.

00:13:37 No?

00:13:38 Then opt for sturdy shoes with a solid sole.

00:13:42 In this case, you won't be barefoot

00:13:45 on a scorching tarmac or in the wild.

00:13:50 Don't put heavy objects in the upper compartments.

00:13:53 In the event of a strong turbulence,

00:13:55 these objects may not stay inside

00:13:57 and, if they do, you may get hurt or other passengers.

00:14:01 That's why, if it's difficult to lift an object

00:14:03 to place it in the upper compartment,

00:14:05 it's better to put it under the seat in front of you or elsewhere.

00:14:09 Don't blame the pilot for a sudden landing.

00:14:12 If you experience it in bad weather,

00:14:14 it may be intentional.

00:14:16 If the runway is covered with water or snow,

00:14:18 the plane must touch the ground hard

00:14:20 to break the water layer or avoid aquaplaning.

00:14:24 Otherwise, water could play the role of lubricant

00:14:26 and the plane could neither brake nor respond to any command.

00:14:31 Deploying an emergency flip-flop

00:14:33 when there is no emergency is a very bad idea.

00:14:37 This can lead to several-hour delays

00:14:39 and cost thousands of dollars to airlines

00:14:42 to put the flip-flop back in its container.

00:14:45 If you're wondering why someone would do such a thing,

00:14:48 some seem to think it will help them get off the plane faster.

00:14:54 Don't ignore the instructions of the staff

00:14:56 to open the flip-flops' doors

00:14:58 during take-off and landing.

00:15:00 In case of emergency,

00:15:01 this will allow them to see what's going on outside,

00:15:03 assess the situation and act quickly

00:15:06 by organising the evacuation.

00:15:08 For example, if there is a fire in front of an exit,

00:15:10 they will redirect the passengers to another exit.

00:15:14 Avoid bringing spray deodorants

00:15:16 or shaving foam in your hand luggage.

00:15:19 These two products tend to explode in mid-flight

00:15:21 and are therefore not allowed on board.

00:15:24 It is preferable to opt for stick deodorants.

00:15:28 External batteries should not be in registered luggage either.

00:15:32 And if you want to bring one on board,

00:15:34 its capacity must not exceed 20,000 mAh per hour.

00:15:37 In addition, you should not use them during the flight

00:15:40 as they may catch fire.

00:15:41 In general, lithium batteries can be used safely,

00:15:45 but as they are very powerful,

00:15:46 they can catch fire if they are not treated carefully,

00:15:49 if they are misused or if there is a manufacturing defect.

00:15:52 Such batteries were the cause of several fires on board,

00:15:56 as well as during ground manoeuvres.

00:15:58 Do not worry about the airport scanners.

00:16:01 They are not dangerous to your health,

00:16:03 otherwise airport staff

00:16:05 would not be able to approach them without special clothing.

00:16:07 Even when you pass in front of a baggage scanner,

00:16:09 the risk is minimal.

00:16:11 And finally, do not behave badly on board.

00:16:14 Have a respectful attitude towards the staff and other passengers.

00:16:17 And also, never try to land a plane alone.

00:16:20 It's not a joke.

00:16:23 In movies,

00:16:24 we sometimes see the main character

00:16:25 taking the controls of the plane instead of the pilots.

00:16:31 Unfortunately, it is almost impossible in real life.

00:16:36 Even if a person is very talented,

00:16:38 loves computer simulators and is ready to follow all the instructions from the ground,

00:16:44 she may fail,

00:16:46 because of a simple factor.

00:16:48 Stress.

00:16:50 It is true that there have been some cases

00:16:52 where amateurs landed small private planes

00:16:54 after the inability of a pilot.

00:16:58 But there have never been cases

00:17:00 where a non-pilot landed a plane.

00:17:05 It only exists in movies.

00:17:08 You log in to your hotel room,

00:17:10 you connect to Wi-Fi,

00:17:11 you jump on the bed

00:17:12 and you publish 15 photos of your new view from the window.

00:17:15 Once the initial excitement has passed,

00:17:17 you notice a suspicious flashing light on your huge TV.

00:17:22 Could it be that someone is watching you?

00:17:24 Or have you just seen too many spy movies?

00:17:27 There are hidden cameras of all shapes and sizes.

00:17:31 The big ones are easy to spot,

00:17:33 but the small ones can be as sneaky as they are discreet.

00:17:37 They can be hidden behind furniture,

00:17:39 in decorations or ventilation nozzles,

00:17:41 and everywhere you will have trouble noticing them.

00:17:44 There are even special cameras

00:17:46 that can be hidden in everyday mobile objects

00:17:49 like alarm clocks, frames, vases and lamps.

00:17:53 Make sure that these objects are not oriented at a strange angle,

00:17:56 or that they are not placed in a way

00:17:58 that gives you the best view of your bed or bathroom.

00:18:02 The easiest way to spot a hidden camera

00:18:04 is to look for the reflection of the lens,

00:18:06 because all cameras are equipped with it.

00:18:09 Turn off the lights and slowly scan the room

00:18:11 with a flashlight,

00:18:12 a laser pointer

00:18:14 or a special wireless spy camera detector.

00:18:17 These are equipped with infrared light and lighting.

00:18:21 As soon as you discover a reflective red dot,

00:18:23 you have to turn on the flashlight

00:18:25 to check if there is a hidden camera.

00:18:28 Check the ventilation nozzles

00:18:29 and all other holes and gaps in the walls or ceiling.

00:18:33 Some advanced detectors even show what the camera sees,

00:18:36 which greatly facilitates tracking and deactivation.

00:18:40 However, these detectors only work on lit cameras

00:18:44 and are constantly working.

00:18:47 Your mobile phone can also help you

00:18:49 to detect these hidden threats.

00:18:51 Turn on Bluetooth and walk around.

00:18:53 Look if unknown devices appear on the screen.

00:18:57 Another idea is to install a network scanning app

00:19:00 that displays all devices connected to the Wi-Fi network

00:19:03 you use at the hotel.

00:19:05 Once the scanning is complete,

00:19:07 study the list to find devices

00:19:09 with a name such as "camera IP" or "cam".

00:19:13 In addition, you can put your phone in selfie mode,

00:19:16 turn off the light and close the curtains,

00:19:18 and look slowly around the room

00:19:20 while focusing on the screen.

00:19:22 Keep your eyes open to spot any white or purple light.

00:19:27 You can still play detective,

00:19:29 call a friend or a family member

00:19:31 and start looking around your room.

00:19:34 Hidden cameras should emit a kind of radio frequency.

00:19:37 It is very likely that this interferes

00:19:39 with the signal of your phone call.

00:19:42 If you start hearing strange noises

00:19:44 while you are on the phone in a specific part of your room,

00:19:47 inspect it carefully.

00:19:51 Check the switches, power outlets,

00:19:53 lamps and other objects you would normally not pay attention to.

00:19:57 If they look a bit crooked,

00:19:59 if they have a hole or if they seem badly placed,

00:20:02 it may be a sign that someone has trafficked them.

00:20:05 Many spying devices need wires

00:20:07 and the person who installed them must have hidden these wires,

00:20:10 often behind a vinyl plate.

00:20:13 This is why the place where the floor and the wall meet

00:20:16 is another area to inspect.

00:20:19 Crests, bumps or discoloration

00:20:21 can be signs that a microphone is hiding.

00:20:24 The same goes for stains on the ceilings and walls,

00:20:27 even if they are not larger than a coin.

00:20:31 If you find a hidden camera or something suspicious,

00:20:33 do not hesitate to inform the hotel or the reservation service.

00:20:38 Do not try to touch or move the device yourself.

00:20:42 If the hotel is not at all, you can contact the police.

00:20:46 After checking that there is no camera in the room,

00:20:49 check the mirrors.

00:20:50 Someone could be watching you from the other side.

00:20:53 Start by checking if the mirror is embedded in the wall

00:20:56 or if it can be adjusted.

00:20:59 If it is a stainless mirror, it will be embedded in the wall.

00:21:02 You can do a simple test to inspect your mirror.

00:21:06 Press the tip of your finger on the glass

00:21:08 and push hard enough to leave a fingerprint

00:21:11 when you remove your finger.

00:21:13 Study the fingerprint.

00:21:15 If there is a small space between the fingerprint and the mirror,

00:21:17 where the glass should be,

00:21:20 it is a mirror.

00:21:21 On a stainless mirror, there is no such space.

00:21:25 Another way to check if your mirror is semi-transparent

00:21:28 is to tap the glass.

00:21:31 If someone is watching you from the other side,

00:21:33 the mirror will emit a hollow sound.

00:21:35 A stainless mirror should seem brighter

00:21:37 on the other side than yours.

00:21:40 Come closer to the mirror and put your hands in a visor around your eyes.

00:21:43 Do you see light behind the mirror?

00:21:46 If so, you may be an inopportune visitor.

00:21:50 Before leaving your room or going to bed,

00:21:52 make sure all the doors are closed.

00:21:54 Through each door, you can hear not only the entrance to the room,

00:21:58 but also the door leading to the balcony, if you have one.

00:22:01 You can bring a portable lock for more security

00:22:04 if you are about to go to bed.

00:22:06 You can also get started on a little DIY project

00:22:09 and wrap a belt or strap around the handle that closes the door.

00:22:14 Tie it up and wrap it around several times for extra protection.

00:22:18 Another idea for a serene nap

00:22:20 is to put your personal belongings near the door.

00:22:23 Glasses and cups will do the trick.

00:22:27 If someone tries to enter while you are sleeping,

00:22:29 there will be noise.

00:22:31 Intruders prefer to remain discreet.

00:22:34 It is therefore very likely that they will immediately give up on you.

00:22:38 If you travel with valuables

00:22:40 and you don't feel comfortable leaving them unattended,

00:22:42 you can put them in the safe in your room.

00:22:45 But since these safes use access codes instead of physical locks,

00:22:49 someone in the hotel must necessarily know the code to unlock it, just in case.

00:22:54 You can therefore bring your own safe.

00:22:57 Some are even sold like books on the Internet, for example.

00:23:00 They are made of solid metal and textured paper

00:23:03 and are equipped with a combination lock.

00:23:05 They usually have enough space to contain your passports,

00:23:08 your cash and your jewelry.

00:23:10 If you have to leave your laptop in the room

00:23:13 and you want to make sure that no one plugs in a USB key to steal your data,

00:23:17 here's what you can do.

00:23:18 Leave a bottle of water or another object next to the USB port.

00:23:22 Measure the distance, assuming it is 1 or 2 cm.

00:23:26 In order for someone to plug their gadget into the laptop,

00:23:29 they will necessarily have to move the bottle.

00:23:31 You can go further and place a pen parallel to the laptop at a certain angle.

00:23:37 You can measure the angle with your smartwatch or your phone,

00:23:40 using the compass app.

00:23:42 Again, if someone moves it, you will know immediately.

00:23:46 Even something as simple as a panel not being disturbed

00:23:49 can help you know if someone has entered your room while you were away.

00:23:53 Pretend you left in a hurry

00:23:55 and the panel accidentally got stuck between the door and its frame.

00:23:59 If you come back and the panel is freely hanging,

00:24:01 it means someone ignored it and tried to disturb you.

00:24:05 In this case, you can contact the reception

00:24:07 and ask if someone is entering the room with you to ensure your safety.

00:24:13 If you care as much about the cleanliness of your room

00:24:15 as you do about your personal safety and business,

00:24:18 this advice is for you.

00:24:21 Hotel staff are normally required to take care of 20 rooms

00:24:24 per 8-hour shift.

00:24:26 This means they won't have more than 30 minutes to take care of your room.

00:24:30 This gives them enough time to make the bed,

00:24:33 clean the floor of the room and the bathroom,

00:24:35 empty the trash and dust off all surfaces.

00:24:39 But they rarely have time to take care of small objects

00:24:41 like switches, door handles and drawers or remote controls.

00:24:46 Yes, these are exactly the objects you will be in contact with the most.

00:24:51 They can even receive more germs than toilets.

00:24:54 So, if you want to be sure that these germs won't land on your hands,

00:24:57 take enough antibacterial wipes

00:25:00 to clean all these objects before touching them.

00:25:03 Are the letters SSSS on your boarding pass

00:25:06 a reason to worry?

00:25:09 What is much more dangerous than turbulence?

00:25:12 Should you try to be the first to board the plane?

00:25:14 You are about to find out.

00:25:17 You may have noticed that most planes have blue seats.

00:25:23 There is no mystery.

00:25:24 Airlines choose this colour

00:25:26 because it is considered to have a calming effect.

00:25:29 This colour is supposed to make passengers feel comfortable

00:25:32 and even help the most nervous passengers to relax.

00:25:36 But there is also another more practical reason.

00:25:39 The stains, dirt and traces are less visible on a dark fabric.

00:25:46 Never throw your boarding pass in a public place.

00:25:48 It contains tons of sensitive information about you,

00:25:51 including your name and your frequent passenger number.

00:25:54 This information can allow someone else to check your future reservations,

00:25:58 change your seat or even cancel your flights.

00:26:02 The best way to manage a boarding pass you have already taken

00:26:06 is to take it home and put it in a paper grinder.

00:26:11 By the way, if you see the letters SSSS or S on your boarding pass,

00:26:17 prepare for additional security checks.

00:26:19 Instead of these letters, there may be a pattern of stain.

00:26:23 Anyway, if you have one of these marks,

00:26:25 your baggage can also undergo a thorough inspection.

00:26:29 But why could they choose you for a secondary check?

00:26:33 Some of these criteria are to make a reservation for a simple trip

00:26:36 or to pay your ticket in cash.

00:26:38 In some cases, the selection is also totally random.

00:26:43 Look, your door is open and the boarding has started.

00:26:46 Wait, where are you going in a hurry?

00:26:48 No need to hurry.

00:26:50 The trick of experienced globetrotters is to always embark last.

00:26:54 First, you don't waste time queuing.

00:26:57 Then, there are fewer people on the platform and in the aisle.

00:27:01 And you finally spend less time on the plane.

00:27:03 Anyway, no one will take your seat, you know.

00:27:06 However, there is an exception.

00:27:08 If you have a bulky baggage,

00:27:10 it may be more wise not to embark last.

00:27:12 Otherwise, there is a good chance that the entire baggage compartment

00:27:15 will be occupied before you arrive at your seat.

00:27:19 Your baggage could then be found in another part of the plane

00:27:22 and you will have to wait for the other passengers to land

00:27:24 before you can pick it up.

00:27:26 Flute!

00:27:28 Before take-off and landing,

00:27:30 the boarding agents usually activate a small switch on the toilet door.

00:27:34 This prevents it from opening when it is not supposed to.

00:27:37 With the same ease, a boarding agent can open the door

00:27:40 when someone is inside.

00:27:42 Just lift the toilet panel

00:27:44 and put your wrist in the unlocked position.

00:27:49 Pilots don't really care about turbulence.

00:27:51 That's because they know that there is something much more dangerous

00:27:53 than any turbulence.

00:27:55 The ascending currents.

00:27:57 In most cases,

00:27:58 the turbulence makes you fall only a few meters,

00:28:01 even if you feel like you're falling from the Empire State Building.

00:28:06 If the turbulence is strong enough

00:28:08 for the pilots to ask the air hostesses to sit down,

00:28:10 the plane can go down from 3 to 6 meters.

00:28:13 But in fact, the most extreme and violent turbulence

00:28:16 are very rare.

00:28:17 An ascending current is a large mass of air,

00:28:20 which is part of a storm or another meteorological phenomenon

00:28:23 that moves upwards.

00:28:25 However, pilots don't see the ascending currents on their radar at night.

00:28:28 And when a plane meets one,

00:28:30 it's as if it was flying over a huge doden at 800 km/h.

00:28:34 An ascending current is also extremely dangerous,

00:28:37 because it can push a plane up to dangerous altitudes.

00:28:44 Modern planes are equipped with a special system

00:28:46 that detects other planes,

00:28:48 mountains and different solid objects along their trajectory.

00:28:51 At 16 km from another plane,

00:28:53 and a voice in the cockpit,

00:28:54 it starts repeating "traffic, traffic".

00:28:58 8 km more,

00:28:59 and the same voice starts giving instructions to the pilot.

00:29:04 Planes can operate with a single engine,

00:29:06 even during take-off and landing.

00:29:08 A simultaneous breakdown of the two engines is almost impossible to imagine.

00:29:12 But in this case,

00:29:13 a plane wouldn't fall from the sky like a stone.

00:29:16 Pilots would have up to 20 minutes to find a suitable landing spot.

00:29:21 The way the cockpit is pressurized has a significant effect on your taste buds.

00:29:25 You lose up to 30% of your ability to taste sweet and salty things.

00:29:31 In other words,

00:29:31 it's not that the food served on planes is not tasty,

00:29:34 but you don't taste their flavour.

00:29:36 It's also the main reason why catering companies,

00:29:39 airlines,

00:29:40 add salt and spices to the dishes they prepare.

00:29:43 But do you know what could help you?

00:29:45 Soundproof headphones.

00:29:47 For a mysterious reason,

00:29:48 which probably has a scientific explanation,

00:29:51 cutting all the ambient noise can help your taste buds.

00:29:55 Each of these "ding" you hear during the flight also has its own meaning.

00:29:59 In most airlines,

00:30:01 a "boom" shortly after take-off

00:30:03 indicates that the landing gear is retracting.

00:30:05 Three consecutive "ding" means there is more emergency than one.

00:30:10 A high-pitched sound

00:30:11 tells the crew members that their colleagues need them in another part of the plane.

00:30:16 Three low-pitched sounds mean there is serious turbulence to come.

00:30:20 The crew members are supposed to put the food trucks away,

00:30:23 take their seats and fasten their seatbelts.

00:30:27 If you are a nervous passenger,

00:30:28 choose a seat in the middle of the cabin.

00:30:30 Turbulences mainly affect the front and rear parts of the cabin.

00:30:34 The central part, which is above the wings, does not shake as much.

00:30:39 Pilots and co-pilots take different meals.

00:30:42 The reason for this precaution is very simple.

00:30:44 Imagine that the two pilots eat the same dish

00:30:46 and that they have a food poisoning.

00:30:49 In this case, neither of them will be able to control the plane.

00:30:54 If they still want to have the same dish

00:30:55 and do not want to accept to take something else,

00:30:57 there is a safety net.

00:31:00 Pilots do not take their meals at the same time.

00:31:02 If a pilot has eaten the dish and still feels well several hours later,

00:31:06 the other pilot can also take his meal.

00:31:10 What would you say if you were asked

00:31:11 what is the most disgusting place on a plane?

00:31:14 No, it is not the toilet seat.

00:31:16 It is not even in the toilets.

00:31:19 Air hostesses recommend paying particular attention to headrests,

00:31:22 seat covers, tablets and seat belts.

00:31:26 Experiments have shown that a third of all seat belts

00:31:29 are covered with fungi and mold.

00:31:32 Most tablets are covered with bacteria.

00:31:35 Seat covers are also very dirty.

00:31:38 But headrests are the dirtiest of all.

00:31:41 In most cases, flight attendants do not have time to change them

00:31:44 or disinfect them between flights.

00:31:48 If the flight attendant announces

00:31:52 that he is finishing administrative formalities,

00:31:55 it means that he is busy reviewing the flight itinerary

00:31:57 or waiting for the ground staff to prepare the flight book.

00:32:00 This is a journal that contains the official report of a trip.

00:32:04 Some planes, especially long-haul aircraft,

00:32:07 have secret rooms where crew members can rest.

00:32:11 These rooms, called crew rest compartments,

00:32:14 are located at the back of the plane or behind the cockpit.

00:32:18 Such a compartment can hold up to 10 comfortable beds

00:32:21 where flight attendants can rest.

00:32:24 The windows of the plane are made of super-resistant plexiglass

00:32:28 which can easily withstand high speeds.

00:32:30 The windows have a special shape,

00:32:32 so that the high pressure inside the cabin

00:32:34 pushes them against the fuselage of the plane.

00:32:38 In other words, the windows of the plane

00:32:40 are very unlikely to break.

00:32:44 In the past, the windows of the plane were square,

00:32:46 but the pressure accumulated in the corners of these windows,

00:32:49 which made them weak points par excellence.

00:32:52 This means that each square window had four weak points.

00:32:56 They were therefore likely to crash

00:32:58 under the enormous pressure of high altitudes.

00:33:01 Fortunately, the design of curved plane windows

00:33:04 has solved this problem once and for all.

00:33:06 This shape distributes the pressure

00:33:08 and reduces the probability of cracks or any other damage.

00:33:12 Planes are regularly hit by lightning,

00:33:15 at least once a year or once every 1,000 hours of flight.

00:33:19 Nowadays, it's totally safe.

00:33:22 The electric charge simply passes through the aluminum hull of the plane.

00:33:26 It does no damage to the plane.

00:33:29 But did you know that planes are not only hit by lightning,

00:33:32 but that they also trigger it?

00:33:36 When a plane crosses a cloud,

00:33:37 the friction between its fuselage and the air

00:33:40 creates static electricity.

00:33:42 And sometimes, it can cause lightning.

00:33:48 Everyone loves holidays,

00:33:49 but deciding what to put in your suitcase

00:33:51 can be a discouraging task,

00:33:53 especially when you are limited by weight and space.

00:33:56 You will probably buy souvenirs

00:34:00 during your long-distance trip.

00:34:02 You will therefore need extra space

00:34:04 when you return for all these items.

00:34:06 Over-stacking or volume can cost you dearly

00:34:10 to the airline company

00:34:12 if you are not properly prepared.

00:34:13 But you can now relax

00:34:15 and focus on booking your holidays.

00:34:18 We will take care of the luggage part

00:34:20 with these travel tips.

00:34:23 There is no doubt that your clothes

00:34:24 will occupy most of your suitcase,

00:34:27 knowing that most airlines

00:34:29 allow one luggage for most short flights

00:34:31 and up to two luggage for long-distance flights.

00:34:34 This does not leave you much space

00:34:35 if you plan to be fashionable

00:34:37 during your escape, especially in winter.

00:34:40 However, this does not mean

00:34:42 that you have to put your underwear upside down

00:34:44 to use them more than once.

00:34:46 The key here is to be clever

00:34:48 with the way you store your suitcase.

00:34:50 First of all, you can think about

00:34:52 how you will fold your clothes.

00:34:54 The most effective way to put your wardrobe

00:34:57 in a suitcase is to roll each item.

00:34:59 Think of your clothes as those sleeping bags

00:35:01 that you brought to go camping.

00:35:04 They always seemed too thick for their compact cover,

00:35:07 but with perseverance,

00:35:08 you managed to roll them tight enough

00:35:11 to hold them inside.

00:35:13 You don't even have to force as much with your clothes,

00:35:15 but the same principle applies here.

00:35:18 Start by carefully folding your shirts,

00:35:20 your pants and everything you plan to pack,

00:35:22 as you could find them in a clothing store.

00:35:25 Then, when you put them in a relatively rectangular

00:35:28 or square shape, roll them tight.

00:35:30 Now that you have your little clothes bags,

00:35:32 start packing them in your bag.

00:35:34 And there you go, you have extra space.

00:35:37 Here is an experience that we all had

00:35:39 when arriving at our vacation spot.

00:35:41 We drop our suitcase on the hospital bed,

00:35:44 we open it to discover all our clothes

00:35:47 unrolled and spread out

00:35:48 as if a tornado had crossed our suitcase.

00:35:51 Your luggage has made a difficult journey from home

00:35:53 to your vacation destination.

00:35:55 It has been dragged along the airport terminals,

00:35:58 swung by the baggage carriers

00:35:59 and thrown back and forth

00:36:01 as the turbulence flies.

00:36:03 A simple piece of paper,

00:36:05 which is nothing more than elastic bands,

00:36:06 will help you keep your clothes well-organized.

00:36:09 Now that you have rolled them,

00:36:10 put a few elastic bands all around

00:36:12 to prevent them from unfolding.

00:36:15 Here is a particularly useful tip

00:36:17 if you want to roll a suit in one piece.

00:36:20 You may have a set of jeans

00:36:21 that you can't wait to wear when you're on the run.

00:36:24 Fold your clothes as before,

00:36:26 then stack the different elements

00:36:28 of your ideal outfit.

00:36:30 Roll them like a whole,

00:36:31 then use the elastic bands to hold them together.

00:36:34 You can plan your outfits every day

00:36:37 before even getting on the plane.

00:36:39 However, you may prefer to fold some clothes,

00:36:42 especially elegant shirts and work pants.

00:36:44 Fortunately for you,

00:36:46 we have a tip for that too.

00:36:48 Instead of folding each item individually,

00:36:50 spread them out on top of each other.

00:36:53 Start with your summer shirts,

00:36:54 alternating one on the right and one on the wrong,

00:36:57 and keeping the collar of your shirts in the center.

00:37:00 Then move on to the pants and smaller items

00:37:03 until they are all flat.

00:37:05 Try to keep your pants in the middle.

00:37:07 Finally, start folding your items on themselves,

00:37:10 the shirts creating the outer layer

00:37:12 until you get a nice, neat package,

00:37:15 like a gift.

00:37:16 You should be able to place your package

00:37:17 straight into your bag.

00:37:19 Do you want to save even more space in your luggage?

00:37:21 Instead of putting your underwear and socks

00:37:23 in their own section,

00:37:24 try to place them in the spaces and spaces

00:37:27 available in the rest of your stuff.

00:37:29 If you plan to take a cap, for example,

00:37:32 the inside of your head cover is an excellent space

00:37:35 to store your socks.

00:37:36 This also applies to other small items,

00:37:39 like magazines and ties.

00:37:41 But don't forget that you can also

00:37:43 put your ties and flat belts on your clothes,

00:37:46 in your suitcase, to save space.

00:37:48 And if you are really limited by the size of your luggage,

00:37:51 let's say you only have one luggage

00:37:53 for a two-week trip,

00:37:54 here's another method.

00:37:56 Get compression bags to store your clothes.

00:37:59 These bags allow you to compact

00:38:01 several sets of clothes

00:38:02 in the size of a small laptop case.

00:38:05 Fold the clothes you plan to take

00:38:08 and store them in the compression bag.

00:38:10 You should be able to put 8 to 10 standard clothes

00:38:13 or a few bulky clothes.

00:38:15 Once you've filled the bag,

00:38:17 close it and expel the air

00:38:18 through the integrated unidirectional pressure valve.

00:38:21 The easiest way to do this is to roll it.

00:38:24 You know how to do it now.

00:38:25 Or press it with your knees.

00:38:28 You should be able to fit 2 to 4 of these compression bags

00:38:31 in a standard hand luggage,

00:38:33 which is particularly useful

00:38:34 if you want to save money

00:38:36 by avoiding registered luggage.

00:38:38 You can take even more clothes on board with you

00:38:41 if you put them in a pillowcase.

00:38:43 The best thing about this tip

00:38:44 is that it will also serve as a comfortable pillow

00:38:47 on which you can rest your head during the flight.

00:38:50 If you have a little more space available,

00:38:53 packing cubes are another excellent way

00:38:55 to keep your things organized.

00:38:58 It may not be as efficient in terms of space

00:39:01 as compression bags,

00:39:02 but many travelers prefer them

00:39:04 to a more tidy packaging.

00:39:06 You can divide them by outfit or type of clothing,

00:39:08 for example one for the pants and one for the top.

00:39:12 You can easily buy packing cubes

00:39:14 on most online shopping sites

00:39:16 and in travel and camping stores.

00:39:18 There are also specially designed packing cubes

00:39:21 for one or more pairs of shoes.

00:39:23 It's an excellent way to compact the space

00:39:26 that your shoes would otherwise take in your luggage

00:39:28 and prevent your own clothes from coming into contact with it.

00:39:32 Nobody wants their clothes to smell like feet, right?

00:39:35 If you still have trouble carrying all your items in your suitcase,

00:39:38 there are a few other tips you can use

00:39:41 to get this little extra space

00:39:43 without additional costs.

00:39:45 The easiest way is to use your own body

00:39:47 with the layers technique.

00:39:49 Choose all the bulky items

00:39:51 and wear as many as you can on you.

00:39:53 You can try to wear a short under your pants

00:39:56 or several layers of your winter clothes,

00:39:58 like your sweater, your jacket and your coat

00:40:00 superimposed on top of each other.

00:40:02 You may sweat a little,

00:40:03 but most airports and planes are well air-conditioned

00:40:07 and you can always get rid of a few layers

00:40:09 once you've boarded the plane.

00:40:11 At least you'll have warm clothes to cover yourself in

00:40:14 if you're cold during the flight.

00:40:15 If you don't want to wear all your layers,

00:40:17 there's another type of bag

00:40:19 that you can carry around for free on the plane.

00:40:21 Get one or more Beautyfui bags.

00:40:24 In one of the airport's shops,

00:40:26 you can even keep them for next time.

00:40:29 Put all your extra items in your Beautyfui bag

00:40:32 and carry them on your flight without additional costs.

00:40:36 It's also worth thinking about the type of luggage

00:40:39 you're using and especially its weight.

00:40:41 A lot of people forget that the standard weight of 7 kilos

00:40:44 allowed by most airlines

00:40:46 includes the weight of their empty luggage.

00:40:49 However, this luggage can often weigh up to 2 to 3 kilos,

00:40:52 which is a large part of the weight

00:40:54 allowed for the container only.

00:40:56 So when you buy your luggage,

00:40:58 consider its weight.

00:40:59 By choosing a lighter bag,

00:41:01 you'll have more weight for the items you want to carry.

00:41:04 Take some of these practical tips

00:41:06 and you won't miss any space or money for your holidays.

00:41:09 Have a good trip!

00:41:11 Airports are one of the most visited

00:41:15 and at the same time the most mysterious places.

00:41:18 Let's find out what's going on behind the scenes

00:41:20 and what secrets they're hiding.

00:41:23 Some airports employ special people called profilers.

00:41:27 These people give life to a program called SPOT,

00:41:30 Screening Passengers by Observation Technique,

00:41:33 which could translate as

00:41:34 "Passengers are being analyzed by observation".

00:41:36 They analyze their gestures and behavior

00:41:38 to detect suspicious people.

00:41:40 Their job is to notice signs of non-verbal anxiety,

00:41:44 people biting their lips,

00:41:46 scratching their heads or looking around them.

00:41:49 If a profiler notices that a person is acting in an unusual way,

00:41:52 he can subject her to an inspection

00:41:54 during which he will question her

00:41:56 to find out more about her

00:41:57 and confirm or deny her suspicions.

00:42:00 Airport agents can also watch you

00:42:02 as you walk between the security control

00:42:05 and your boarding gate.

00:42:07 Some airports have facial recognition scanners

00:42:10 that can easily track you.

00:42:12 They are equipped with a special software

00:42:14 that compares the face of passengers

00:42:16 with their identity documents.

00:42:18 Don't forget that if you don't charge your laptop

00:42:21 before the flight, it can be confiscated.

00:42:24 It's not uncommon for a security agent

00:42:26 to ask you to turn on your device to check it.

00:42:29 If you don't do so,

00:42:30 your gadget can be taken for additional inspection.

00:42:34 For security reasons,

00:42:35 it is crucial to ensure that it has not been trafficked

00:42:38 or modified in a way that could cause damage during the flight.

00:42:42 Carrying an electric toothbrush in your luggage

00:42:45 can cause you trouble.

00:42:47 Some manufacturers' brushes contain lithium batteries

00:42:51 and these can cause serious problems during the flight.

00:42:55 That's why leaving your electric toothbrush

00:42:58 in your luggage is not an option.

00:43:00 But you can put it in your hand luggage.

00:43:03 And if it works with standard batteries,

00:43:06 you can put it wherever you want.

00:43:09 Everyone who has ever taken a plane

00:43:11 knows the rule of liquid ban.

00:43:13 But not everyone knows that this rule

00:43:15 also applies to peanut butter, toothpaste,

00:43:18 cream, lotion, liquid makeup,

00:43:21 washing lamps, snowballs,

00:43:23 certain types of drugs, deodorants,

00:43:26 and even frozen shoe soles.

00:43:30 Now let's look at the landing runway.

00:43:34 Airports pay airlines a huge amount of money

00:43:37 to land on their runway on certain days and at certain hours.

00:43:42 But the most interesting thing is that these times can be exchanged.

00:43:46 For example, in 2016,

00:43:48 Oman Air paid Air France about 75 million dollars

00:43:52 for a early arrival time at London's S-Row airport.

00:43:56 You may have noticed that the price of plane tickets

00:43:59 has increased over the last decade.

00:44:02 It's because of the extremely high price of landing times.

00:44:06 Flight controllers not only control the planes in the sky,

00:44:10 as we often see in movies,

00:44:12 but they also take care of their ground movement.

00:44:14 They also control the lighting of the runways.

00:44:18 There are three types of air traffic controllers,

00:44:20 on-route, terminal, and tour.

00:44:23 Each of these controllers has its own area of responsibility.

00:44:27 A flight controller has about five screens,

00:44:30 and the information displayed on them changes constantly,

00:44:33 because the screens display weather conditions

00:44:35 and information about other planes.

00:44:38 If you show up at the security check,

00:44:41 and you find out that you have something forbidden in your luggage,

00:44:45 don't worry.

00:44:46 You still have a chance to save your favorite Swiss knife.

00:44:49 Some airports have post offices,

00:44:53 and you can send your luggage to the address you want.

00:44:56 However, shipping costs are quite high,

00:44:58 and some items are forbidden to be shipped.

00:45:02 Airports can quickly resell your lost luggage.

00:45:06 Of course, you have a chance to get your luggage back,

00:45:08 which has traveled to another destination.

00:45:11 But it's just as likely that you'll never see it again.

00:45:15 Airports have the right to sell lost items

00:45:17 during a auction.

00:45:19 Most airports organize a lost luggage sale every year.

00:45:24 After paying for an entry ticket,

00:45:25 you can buy electronic devices,

00:45:28 clothes, bags, and other items.

00:45:31 You may travel on the same flight as a star,

00:45:34 but you won't know it.

00:45:35 Large airports have separate recording and security procedures

00:45:39 for celebrities.

00:45:40 They often board the plane

00:45:41 directly through a hidden door next to the runway.

00:45:46 Some airlines also use private vehicles

00:45:49 to transfer VIP passengers from the terminal to the plane.

00:45:53 Most passengers arrive at the airport well in advance.

00:45:57 And the most popular activity while waiting for a flight

00:46:00 is to walk around the T-Free area.

00:46:03 And even if people rarely plan to buy anything there,

00:46:06 several products end up in their baskets.

00:46:09 That's because many airports are specially designed

00:46:12 to make people feel relaxed and comfortable.

00:46:16 There are large windows,

00:46:17 lots of light, and comfortable seats.

00:46:20 Statistically, relaxed passengers

00:46:23 are 10% more likely to spend money in stores,

00:46:26 T-Free shops, and cafes and restaurants.

00:46:29 Airport designers think a lot about their layout.

00:46:32 This ensures a fluid flow of passengers.

00:46:36 And the main point here is easy navigation

00:46:39 that prevents them from getting lost.

00:46:40 They do this with subtle but very effective clues.

00:46:45 Placing out-of-tax areas between security checkpoints

00:46:48 and boarding points is one of them.

00:46:50 They're supposed to help you relax

00:46:52 after passing security checks

00:46:55 and take you where you need to go.

00:46:57 A famous chef's restaurant at the airport

00:46:59 might not be as good as if you went to a real restaurant.

00:47:03 It's not the chefs themselves,

00:47:04 but special restaurant companies

00:47:06 that are responsible for the points of sale at airports.

00:47:09 One of the reasons for the poor quality of food

00:47:11 and the extremely strict security

00:47:13 around the deliveries at airports,

00:47:16 including food, is that you can always eat a good meal,

00:47:19 but it's not the same thing.

00:47:21 Now let's talk about another way

00:47:23 airports manipulate you to make you spend your money.

00:47:26 They make you go through T-Free shops

00:47:28 directly after security checks.

00:47:31 But the most curious thing is that the aisle

00:47:34 is generally oriented to the left.

00:47:37 That's because most people are right-handed.

00:47:39 That means they use their right arm to pull their luggage

00:47:43 and they tend to look to the right

00:47:45 when they go through the shops.

00:47:47 When the T-Free area curves to the left,

00:47:50 there's more space on the right,

00:47:52 where passengers tend to look the most.

00:47:55 Have you ever noticed the number of mirrors at airports?

00:47:58 They're strategically placed to make airports look bigger

00:48:02 and create a space illusion.

00:48:04 This helps reduce the feeling of claustrophobia

00:48:07 and makes the airport experience more pleasant for travelers.

00:48:11 If you have the choice, don't exchange liquid money at airports.

00:48:14 You'll never get a good rate.

00:48:17 Those who haven't bought local currency in advance

00:48:19 can order it online and get it back at the airport.

00:48:22 Some services only need a few hours of pre-order time.

00:48:27 Or it can be even more judicious to withdraw money

00:48:30 from a distributor at your final destination.

00:48:33 Have you ever paid attention to airport codes?

00:48:36 The most used are the three-letter ones.

00:48:38 Why three?

00:48:39 In the 1930s, in the United States,

00:48:42 pilots used the two-letter VILA codes

00:48:44 of the National Weather Service to refer to airports.

00:48:48 But quickly, the number of airports in the country

00:48:50 exceeded the number of these codes.

00:48:53 That's why airlines expanded this system

00:48:56 by adding a third letter.

00:48:58 That's how LA for Los Angeles became LAX.

00:49:02 But even if there shouldn't be two airports with the same code,

00:49:06 some of these codes are so similar that you can easily confuse them.

00:49:10 For example, an airport in Bangladesh has the CGP code,

00:49:15 while another in Argentina has the CPG code.

00:49:20 Even if they are very far apart,

00:49:22 don't get the wrong destination.

00:49:24 Many airports are built near the water,

00:49:27 and there are a lot of reasons for that.

00:49:29 First of all, most airports are located near big cities,

00:49:32 and big cities are generally built

00:49:35 near a stretch or a stream.

00:49:37 At the time, before the paved roads and trucks existed,

00:49:41 goods were transported by boat.

00:49:43 Having a river or a nearby sea was vital

00:49:46 to deliver essential supplies to cities,

00:49:48 such as food and building materials.

00:49:51 It also allowed trade to stimulate the local economy.

00:49:55 Since most people go to big cities for business and holidays,

00:49:59 rather than rural areas,

00:50:01 it was logical to build airports in these places.

00:50:04 The high demand for travel made airports both necessary and profitable,

00:50:09 but that's not the only reason why they are built near the water.

00:50:12 Big cities are generally very populated,

00:50:15 and airports need huge areas.

00:50:18 Trying to find a large enough area in the middle of New York City

00:50:21 to build an airport would be practically impossible.

00:50:25 The areas near the water are generally a little more rural,

00:50:29 so there is more space than in big cities full of buildings.

00:50:33 Some countries have even pushed this principle a little further.

00:50:36 Land is really rare in Japan,

00:50:38 so to build the international airport of Kansai,

00:50:41 the architects of Osaka went 5 km offshore

00:50:45 in the bay of Osaka to create an artificial island.

00:50:49 Measuring 4 km long by 2.5 km wide,

00:50:53 it is so vast that you can even see it from space.

00:50:56 It took 38 months to complete the construction.

00:50:59 Travelers can go to the main island of Honshu by car,

00:51:03 train or ferry at high speed.

00:51:06 The international airport of Kansai opened in 1994

00:51:10 and became the first airport in the world to be built on the sea.

00:51:14 Despite its location, it has the longest terminal on the planet,

00:51:18 with a length of just under 1.5 km.

00:51:21 Airplanes must not have obstacles around them when they land either.

00:51:25 It would be really difficult to try to land an airplane with obstacles.

00:51:29 This includes trees, mountains, buildings and power lines.

00:51:34 On water, nothing will prevent planes from taking off or landing,

00:51:37 which makes things much safer.

00:51:39 On mountainous islands, the tracks are often parallel to the ocean,

00:51:43 because the mountains are inside the land,

00:51:46 such as at the airport of Gran Canaria,

00:51:49 located on one of the Canary Islands.

00:51:51 This is also explained by security reasons.

00:51:54 If a plane has to cancel its landing on the runway and go around,

00:51:58 it must have enough room to do so safely, without crashing.

00:52:03 It must also be able to go up in the air at a safe angle

00:52:06 to avoid causing problems to passengers.

00:52:09 Reaching this safety altitude is much easier,

00:52:12 faster and safer on the seaside

00:52:14 compared to big cities or mountainous areas.

00:52:17 Speaking of failed landings,

00:52:19 pilots are trained to face an engine failure when taking off.

00:52:22 If a plane reaches the right speed to take off,

00:52:25 it must leave the runway even if the engine breaks down.

00:52:28 But don't worry, planes can still fly with just one engine.

00:52:33 It just requires a little more concentration.

00:52:36 Due to the reduced capacity,

00:52:37 it takes more time to reach the right altitude,

00:52:40 and it takes more space to take off.

00:52:42 By taking off in the direction of the ocean,

00:52:44 it is easier to climb to a safe altitude

00:52:47 without worrying about colliding with any obstacle.

00:52:50 Another reason why airports are built at sea level

00:52:54 is that the higher you go, the less air you get.

00:52:57 This reduces the thrust of the engines

00:52:59 and the lift generated by the wings.

00:53:02 In higher altitudes, it is more difficult for planes to take off.

00:53:06 In terms of money, it means that longer runways must be built,

00:53:10 which would cost more, and no one wants that.

00:53:13 At sea level, planes need less fuel

00:53:16 because they don't burn as much energy when taking off,

00:53:19 and they make less noise because they don't push the engines as hard.

00:53:23 But even if this makes planes less noisy,

00:53:25 airports still have quite high noise levels.

00:53:29 Imagine you hear planes flying over your house

00:53:31 while you try to sleep at night.

00:53:33 This is one of the main reasons why airports are generally built on the coast,

00:53:38 far from any residential area,

00:53:40 because fish are generally not known to file complaints about noise.

00:53:45 In some countries, airports even have to provide improvements

00:53:48 for the neighbouring houses that will be affected by noise.

00:53:52 Germany is one of these countries,

00:53:54 and they do everything from improving roofs to adding a wall insulation

00:53:58 to reduce noise pollution.

00:54:00 Building near the coast means that they won't have to pay

00:54:03 for all these expensive improvements,

00:54:05 which saves a lot of money at the airport.

00:54:08 Coastal areas also have meteorological advantages for flights.

00:54:12 Sea breeze is a regular wind that blows water towards the ground.

00:54:17 Planes usually land and take off in the wind,

00:54:20 which makes it the ideal place to build an airport,

00:54:23 because there won't be any delay due to unexpected strong winds.

00:54:26 But if the sea breeze that comes in spring and summer is great,

00:54:30 areas near the water can be subject to fog in autumn and winter,

00:54:34 so this presents both advantages and disadvantages.

00:54:38 However, not all airports are on the coast,

00:54:41 because they also pose a number of problems.

00:54:43 One of the most important is that of birds.

00:54:46 Our friends in Plume love the coast,

00:54:48 because of all the delicious fish that swim there.

00:54:51 But they can cause big problems for pilots.

00:54:54 But airports manage to avoid this problem

00:54:56 by using intimidation tactics.

00:54:59 Birds don't really like noise,

00:55:01 and planes are not the most silent objects in the sky.

00:55:04 Airports also produce loud noises,

00:55:07 and even use falcons to shoot down birds on their way.

00:55:11 The most obvious risk of building near the sea, however, is flooding.

00:55:15 Airports cost a lot of money to build,

00:55:18 and planes are not cheap either.

00:55:20 In 2018, the Kansai airport was flooded by the Jebi typhoon.

00:55:25 They had to cancel all operations for two days,

00:55:28 and the water was so high that it damaged the plane's engines.

00:55:32 Although coastal airports put in place measures to protect themselves from floods,

00:55:36 it's hard to save everything from a typhoon.

00:55:39 With the rise in sea levels and the increase in extreme weather conditions,

00:55:43 these floods seem more and more likely.

00:55:46 One quarter of the world's most frequented airports

00:55:49 are less than 10 metres above sea level.

00:55:52 And 12 of them, including those in New York, San Francisco and Shanghai,

00:55:56 are less than 5 metres.

00:55:58 Oops!

00:55:59 All this water poses another problem.

00:56:01 If planes cross the runway, they have nowhere to go.

00:56:04 The crossing of the runway occurs mainly

00:56:06 when the pilot underestimates the length of the runway

00:56:09 and does not reach the take-off speed in time.

00:56:11 There are usually additional concrete or grass plates

00:56:14 on which the plane can still fly when the airports are on the ground.

00:56:19 The plane would be a bit damaged in this case, but it's not a big deal.

00:56:22 But with coastal airports, the plane can end up directly in the water.

00:56:27 Fortunately, there is a new technology

00:56:29 that aims to prevent this from happening.

00:56:32 These new systems allow pilots to find out all the flight parameters,

00:56:36 including weather conditions that could affect take-off.

00:56:40 The system then calculates the length of the runway

00:56:42 that the plane will need to stop.

00:56:45 Many airports have also added soft concrete

00:56:48 at the end of the runway to avoid a water disaster.

00:56:51 When the plane slides on this soft concrete,

00:56:53 it gets stuck and this prevents it from flying too far.

00:56:57 Airports built next to water also pose financial problems.

00:57:02 Land rental near the coast or lakes

00:57:04 is generally more expensive than on the mainland

00:57:07 because of the demand.

00:57:09 For example, 40% of the American population lives on the coast,

00:57:13 although coastal areas only account for about 10% of the total land mass in the United States.

00:57:18 Airports need flat ground to be built,

00:57:21 but it's not always easy to find

00:57:23 and coastal areas can cause particular problems

00:57:26 due to sand and swamps.

00:57:28 But that doesn't mean it's not possible.

00:57:31 One of the most famous airports in the world,

00:57:33 New York's JFK airport, was built on swamps.

00:57:37 The land was much cheaper than usual

00:57:40 and swamps can't really be used for much.

00:57:43 Of course, it cost a lot of money to make the ground suitable

00:57:46 to transport heavy loads,

00:57:48 but all this has been fixed.

00:57:50 Finding such a large area near one of the largest cities in the world

00:57:53 was a good luck, even if it was a swamp.

00:57:56 First of all, you probably already know that there are microbes everywhere

00:58:01 and that it is impossible for humans to get rid of them.

00:58:04 These tiny creatures strengthen our immune system.

00:58:08 Our body learns to protect itself by constantly being confronted with bacteria.

00:58:14 So don't worry too much about what's going to happen next, okay?

00:58:17 Welcome to one of the favorite places for bacteria and microbes.

00:58:21 Hotel rooms.

00:58:23 Yes, they seem so clean, but in some respects they are more dangerous than a waste dump.

00:58:29 Where everything is dirty and where you are afraid to touch anything.

00:58:33 But the dirt of hotel rooms is invisible.

00:58:37 Microbes are waiting for it, and there are a lot of them.

00:58:40 The first problems already appear in the elevator.

00:58:44 These buttons are full of various bacteria.

00:58:48 Let's assume they are never disinfected.

00:58:52 It would then become the scene of a deadly fight between billions of microbes.

00:58:57 Take a look at an ordinary residential building.

00:59:00 There are also elevators there.

00:59:02 These inhabitants always transmit the same microbes by pressing the buttons.

00:59:08 Their body gets used to it and quickly develops effective defenses.

00:59:12 But in hotels, residents often change.

00:59:15 A person from such or such a hot country can transmit a bacteria

00:59:18 that will make a person from a cold country sick.

00:59:22 After touching these buttons, it is therefore recommended to wash your hands carefully.

00:59:27 The elevator opens and you head to your room.

00:59:31 Be careful, there is another danger right in front of you.

00:59:34 Do you see the door handle?

00:59:36 It is also covered with microbes.

00:59:39 How many people have touched it before you?

00:59:42 When was it cleaned for the last time?

00:59:45 Do you know why it is more dangerous than a toilet seat?

00:59:50 It is because microbes accumulate on our hands.

00:59:53 When we do not wash them, we transfer bacteria from one place to another

00:59:57 by touching the surfaces of different objects.

01:00:01 The best way is to touch this handle with the same hand

01:00:04 that you used to press the button in the elevator.

01:00:07 As soon as you enter the room, wash your hands.

01:00:11 The good news is that the hotel staff

01:00:13 cleans the bathroom much better than the rest of the room.

01:00:16 You are therefore a little safer here.

01:00:19 But still look at the corners and squares of this room.

01:00:22 If you see black spots somewhere, it means there is mold.

01:00:26 It can cause allergic reactions, nasal discharge, irritation of the eyes, etc.

01:00:31 It can even be quite dangerous,

01:00:33 but the hotel staff is generally very vigilant.

01:00:36 It is therefore unlikely that there is any in your room.

01:00:39 Unless it is a cheap hotel.

01:00:41 But you are careful, aren't you?

01:00:44 By the way, did you know that there are more germs on toilet paper

01:00:47 than on toilet seats?

01:00:51 So it's a mistake to cover the toilet paper window before sitting down.

01:00:54 First, many people will have touched it and left bacteria there.

01:00:59 Then, small splashes come to dirty the roll when you pull the chassis.

01:01:05 Microbes feel more comfortable on paper than on smooth surfaces.

01:01:10 You should therefore lose this habit.

01:01:12 But if the roll is protected by a metal or plastic cover,

01:01:16 there is a good chance that it is sheltered from microbes.

01:01:19 After doing your needs and washing your hands,

01:01:22 you have two options.

01:01:25 Wipe yourself with a paper towel or use a hand dryer.

01:01:29 In one case or another, you will not escape germs.

01:01:33 But if you use the hand dryer, bacteria will fly all over the room.

01:01:37 It is therefore better to take a towel.

01:01:40 When you leave the toilet, don't think your troubles are over.

01:01:45 Microbes are not all harmless.

01:01:48 Some of the most common bacteria in hotels cause intestinal infections.

01:01:53 If you don't want to spend the rest of your holidays next door or on the toilet,

01:01:57 prepare to fight tiny parasite colonies.

01:02:02 The first thing to do is to wash the glasses and cups with soap.

01:02:06 Some travelers bring their own cups and it's a good idea.

01:02:10 Then look around you and ask yourself,

01:02:12 what are the places that people touch the most?

01:02:15 It's the remote control, the coffee maker, the refrigerator,

01:02:19 the handles, the tables, the hair dryer and the windows.

01:02:23 Relax, you don't need to do the housework for the staff.

01:02:27 You just need to have a towel and disinfectant.

01:02:31 Wipe the surface of all these objects.

01:02:33 Maybe you worry uselessly.

01:02:35 This hotel probably takes care of the cleanliness of the rooms.

01:02:38 Or maybe not.

01:02:40 You can also ask for your room to be cleaned again.

01:02:44 You have wiped all the surfaces and you have put yourself in bed exhausted.

01:02:48 Unfortunately, you are not the only one on this soft mattress.

01:02:52 Millions of bacteria keep you company.

01:02:55 Of course, washing pillows and bed linen destroys germs.

01:02:58 But what about the bed cover?

01:03:01 It is very likely that no one washes it.

01:03:03 Eliminating germs on fabric is difficult.

01:03:05 You will probably have to accommodate.

01:03:09 But what is unacceptable are bed dung.

01:03:12 If you notice dark spots on your mattress,

01:03:14 it is very likely to be residues deposited by these parasites.

01:03:18 You're not hungry, are you?

01:03:19 I wouldn't want to cut your appetite.

01:03:22 And there may be dung hidden in the mattress.

01:03:25 They can sleep there for months and wake up one day to satisfy their hunger.

01:03:29 While you are resting, they come out and prick your legs.

01:03:33 If you notice small red spots on your skin,

01:03:35 it is that dung has kissed you.

01:03:39 The pricking of these insects is not dangerous.

01:03:42 Some people may have a mild allergic reaction,

01:03:45 an irritation of the skin.

01:03:47 But the problem is that dung can get into your clothes or luggage

01:03:51 and you risk bringing them back home.

01:03:54 It multiplies rapidly.

01:03:57 So if you don't want to adopt a whole colony,

01:04:01 wash your clothes and luggage and take a shower.

01:04:05 But first, ask the hotel manager to reimburse you.

01:04:08 Dung in the bed is unacceptable.

01:04:10 Even if your room is of impeccable cleanliness,

01:04:13 it doesn't mean there is no dung.

01:04:15 The previous clients may have brought some.

01:04:19 But there are no black spots on your bed

01:04:21 and you have cleaned all the surfaces at risk.

01:04:23 It's OK, you're safe.

01:04:25 Still, wear slippers or thick socks.

01:04:28 Because the floor can also be quite dirty.

01:04:32 You spend several nights at the hotel and you finally return to a clean and safe place.

01:04:36 Your home.

01:04:38 Unfortunately, there can also be a lot of microbes.

01:04:42 Do you like to play video games with your friends?

01:04:46 Do you remember the last time you cleaned your game controller?

01:04:50 All your friends held it in their hands and put all their microbes in it.

01:04:56 Your cutting board.

01:04:58 How do you wash it?

01:05:00 Water asparagus is not enough.

01:05:02 Especially if you cut meat and vegetables.

01:05:05 You can cut zucchini and its germs will stay stuck to the surface.

01:05:09 Then you quickly wash the board and put it back in place.

01:05:12 But the germs haven't disappeared.

01:05:14 They are still well attached.

01:05:16 While you cut bread.

01:05:19 They will jump on your pies and end up in your stomach.

01:05:23 Are you still hungry?

01:05:26 Another dangerous place is your dishwasher.

01:05:28 Even if you use a good detergent, germs still accumulate.

01:05:32 The best way to get rid of them is to change the sponge once a week.

01:05:37 And now, here is the paradise of bacteria.

01:05:40 A place where the temperature is ideally cold and where there is a lot of food.

01:05:44 From the freshest to the most varied.

01:05:45 It's your refrigerator.

01:05:48 You put products that you bring back from the supermarket.

01:05:50 Hundreds of people may have touched them, leaving thousands of germs.

01:05:55 Therefore, don't forget to wash your refrigerator often.

01:05:58 And also, keep all meat away from packaged products.

01:06:02 The germs on a bleeding steak multiply quickly.

01:06:07 Everything I've told you may start to worry you.

01:06:10 If so, remember the advice I'm going to give you now.

01:06:15 You will have much less problems if you wear a Bavarian panty from time to time.

01:06:19 And that you wash your hands regularly.

01:06:22 Check in the corner, under the bed.

01:06:25 Wait, what's hiding here?

01:06:28 Hotels are supposed to be your home far from home.

01:06:31 But do you know what secret they hide?

01:06:34 Here is what no staff or manager will ever tell you.

01:06:39 Some hotel owners are very superstitious about the number 13.

01:06:43 Or they think that customers could be it.

01:06:45 Anyway, it is possible that the 13th room or the entire 13th floor is completely gone.

01:06:52 In the Far East, it's the same for the number 4.

01:06:56 You can easily get an extra free overclocking.

01:07:00 If you are celebrating a birthday or a wedding.

01:07:03 Just call in advance and tell them about the event to come.

01:07:08 You may check the bed to see if there are any spots or insects.

01:07:11 But you probably forget the dirtiest thing in the room.

01:07:15 The TV remote control.

01:07:17 It is not disinfected between each reservation.

01:07:20 But it has a plastic bag in it before you use it.

01:07:23 There is a lot of other dirty stuff in this room, but we'll talk about it later.

01:07:28 Each hotel has a place where the maintenance staff puts the forgotten objects.

01:07:32 The most frequently lost objects are phone chargers.

01:07:36 But more interesting discoveries have been made.

01:07:39 False teeth, glass eyes and even boxes of gum.

01:07:43 If no one comes to look for these strange treasures after 5 or 10 years.

01:07:47 Yes, they are nice enough to wait.

01:07:49 The members of the room staff take out the lost objects from them.

01:07:54 Some luxury hotels may have hidden cameras for security reasons.

01:07:59 The most common place for this is the door's window.

01:08:03 So always stick a piece of tape or mastic on the one in your room.

01:08:07 However, it is not normal that there is a hidden camera in the room itself.

01:08:12 To check it, turn off the light and turn on the front camera of your phone.

01:08:17 Slowly scan the room.

01:08:19 Your device will capture their infrared light.

01:08:22 The most common places are near the bed and in the bathroom.

01:08:25 So check these areas.

01:08:28 The hoteliers often let their friends and family stay for free.

01:08:32 But you don't notice it, since they usually leave before the start of the high season.

01:08:37 The employees and the maintenance staff can also benefit from some advantages.

01:08:42 They can keep the towels, slippers, towels and shampoos.

01:08:46 But what you may not know is that the hotel chains often accept

01:08:51 that you take some objects in the room.

01:08:53 Paperwork and toiletries, coffee cups, umbrellas,

01:08:57 everything that bears their name and logo.

01:09:00 This gives them free advertising when you bring these objects with you.

01:09:05 These beautiful fruits and vegetables near the entrance of the hotel restaurant

01:09:08 are not just a decoration.

01:09:10 They make your body feel full

01:09:13 even before you take your plate.

01:09:16 You eat less and the hotel saves money.

01:09:20 The hotels can give you extra bottles of shower gel or other toiletries.

01:09:25 But some of them make you pay if you took too much food at the breakfast buffet.

01:09:30 And to avoid contradicting the cooks with the amount of food thrown away,

01:09:34 the hotels in some countries make their customers pay for everything that is left unconsumed in the plate.

01:09:40 No hotel chain will tell you how to get the biggest discount for your stay.

01:09:45 So if you have a limited budget, book a room after 6 p.m.

01:09:50 That's when the commercial service tries to sell all the booked rooms at the last minute.

01:09:56 This often means that you have to reduce the price, sometimes by half.

01:10:00 The first Sunday of the month is the best time to register.

01:10:04 The holidaymakers are leaving, the business travelers are not here yet,

01:10:08 so most of the best rooms are available.

01:10:11 To get the best choice, there is a special service called "Rooming".

01:10:16 You can see everything in the hotel and choose the room you like the most.

01:10:20 Just ask the receptionist.

01:10:23 The hotels will not talk to you about their other free services unless you ask them.

01:10:29 Free phone chargers, high school iron, water bottles and board games are part of it.

01:10:35 They can also order a transfer for you, book concert or theater tickets

01:10:39 and wake you up at a specific time.

01:10:42 Hotels can refuse to register you even if you have paid your reservation in advance.

01:10:47 They can sometimes cancel your reservation if you do not show up before a certain time.

01:10:52 If something keeps you on the way, call and notify them in advance.

01:10:56 And even if you arrive on time, you can still be denied a room.

01:11:01 This usually happens when the hotel is overbooked.

01:11:04 In this case, they can redirect you to another hotel.

01:11:07 Even more surprising, the chances of this happening depend on who you are.

01:11:12 Single men, couples and groups of friends will be more likely to refuse than a single family or woman.

01:11:19 This is because the first ones are usually more flexible in the face of an unexpected change.

01:11:24 Before you jump on the minibar, it is better to check if these drinks are sealed.

01:11:29 Hotel employees say that there have been cases where customers have finished all the drinks

01:11:34 and filled the bottles with tap water to avoid paying for them.

01:11:38 Big chains often have their own special transport to pick up important customers

01:11:43 or to get them to move around the city.

01:11:45 Their own taxis are generally cheaper than those in the city,

01:11:48 so if you want to save money, check the cost of their transport at the reception.

01:11:54 But do not ask the receptionist to recommend you the place where you should eat.

01:11:58 He will tell you about a partner restaurant that will pay for the recommendations, even if it is expensive and bad.

01:12:04 Customers do not really pay for the room itself, but for the location of the hotel.

01:12:09 The proximity of the airport, the beach, the city center or famous sites will cost you an additional amount.

01:12:15 Yes, even if it has no stars and the equipment is not of high quality.

01:12:20 Think twice before handing keys to the car driver.

01:12:23 There have been cases where hotel employees took a high-end car for a small trip and filmed themselves in it.

01:12:29 A famous person could stay in the room right next to yours.

01:12:33 No one would know, since they can use fake names to hide their identity.

01:12:38 But for the rest of us, ordinary people, this is not allowed.

01:12:42 You asked for a simple room with a large bed and a beautiful view of the beach,

01:12:47 but you got a room with two small beds and a superb view of a brick wall.

01:12:52 This happens often, but they are supposed to offer a discount or a free service to make up for the difference.

01:12:58 Make this right valid if the receptionist does not offer it to you.

01:13:02 The safe in your room can be anything but safe.

01:13:06 If you have valuables, ask the receptionist to put them in the hotel's main safe.

01:13:11 This place is generally much safer because all the staff is not there.

01:13:16 Even if the hotel's chairs and sofas look clean, wait to see one under a microscope.

01:13:22 Do not sit on them without having previously placed a towel or a blanket.

01:13:26 You do not know if the client who preceded you did not put his feet on them.

01:13:30 However, these feet are certainly dirty, since the carpets of the rooms are rarely cleaned,

01:13:35 or maybe once a year, or less.

01:13:38 So do not walk on them barefoot.

01:13:40 And if you wear slippers or keep your shoes, make sure to pack them when you put them in your suitcase before leaving.

01:13:48 Same thing with the bed.

01:13:50 Before lying down on it, know that the cleaning staff probably wipes the sheets between each client,

01:13:55 but not this big and beautiful bedsheet full of germs.

01:13:58 Do not touch the glasses either.

01:14:00 Even if they get a dry sweep, it is probably with the same dry sweep as the one used to clean the other surfaces.

01:14:06 Why? Because ...

01:14:09 The staff only has 20 to 30 minutes to completely clean each room.

01:14:13 So they have to do it quickly and not in depth.

01:14:17 The things often forgotten are switches, door handles and drawers, remote controls,

01:14:23 and, ironically enough, these are the objects that are touched the most.

01:14:27 Experts have discovered that these objects contain as many germs as toilets.

01:14:31 The solution always brings a lot of antibacterial wipes.

01:14:35 And if you are looking for information on hotel cleaning practices, remember,

01:14:39 "clean" does not mean "disinfect".

01:14:42 Choose your words carefully so as not to allow the manager to miss you.

01:14:47 Hotels are very popular places to visit.

01:14:51 However, cleanliness is not necessarily a priority.

01:14:54 There may be bed dung and other parasites that are only noticed when it is already too late.

01:15:00 Here's a tip.

01:15:02 When you arrive at the hotel and enter your room,

01:15:05 do not rush to open your suitcases and put all your clothes in the cupboards or on the bed.

01:15:10 It is best to leave your luggage in the bathtub and examine the room in search of any parasites.

01:15:17 You have to check all the carpets, furniture, cushions and any other surface that would attract these little animals.

01:15:24 Once the investigation has been carried out, you can unpack your suitcases.

01:15:29 The bathtub is the best place to protect your belongings,

01:15:32 because insects cannot survive there.

01:15:35 So it is impossible for them to infest your luggage while you are not paying attention.

01:15:39 Besides, it would be better if you got rid of this dustpan.

01:15:42 The sheets may be washed regularly, but this is not the case with dustpans.

01:15:46 In some hotels, they are washed once a week, and again.

01:15:51 But in others, they are not washed at all.

01:15:53 The same goes for the litter.

01:15:55 Chic hotels change sheets every day, but many small-price hotels do not change either the pillows or the sheets when another person leaves.

01:16:02 It is better to ask for clean pillowcases as soon as you arrive.

01:16:06 It is also better not to drink in the bathroom glass, because most are not properly washed.

01:16:12 The staff sometimes uses disinfectant or cleaner to make the glasses shine.

01:16:16 Have you ever wondered why they did not use sheets in hotels?

01:16:21 It is convenient for the house, but not really for the hotel structures.

01:16:25 The sheets are changed much more often than at home, and the elastic wears out much too quickly.

01:16:30 It is also a hassle to store the sheets.

01:16:33 You always need to have several of different sizes.

01:16:36 It is therefore more convenient to use two simple sheets to have double beds.

01:16:40 Speaking of sheets, you have surely noticed that in hotels, the litter and the towels are almost always white.

01:16:47 It is first of all a practical question.

01:16:51 You can wash everything together and add water from Javel in case you need to get rid of the stains.

01:16:56 But it is also a matter of comfort for the users.

01:17:00 According to a survey conducted with the hotel clientele,

01:17:05 white is perceived as a fresh and luxurious color that makes the stay more pleasant.

01:17:10 If a hotel room seems to have a too modest price, you have to be careful.

01:17:15 It is possible that the price does not include the service costs.

01:17:19 If you pay for your room in advance, you pay all the stay costs,

01:17:23 namely the initial price of the room at the time of booking,

01:17:26 and all the additional costs, such as the service costs.

01:17:30 By deciding to pay at the hotel at the end of the stay, you can face unexpected costs.

01:17:36 It is better to read the add-on.

01:17:38 You may have noticed that in some hotels, there was a phone in the bathroom, right next to the toilets.

01:17:46 It may seem strange, but it is mandatory for hotels that have received four stars in the United States.

01:17:51 And then, finally, it's not that absurd.

01:17:55 Imagine that you slip and fall into the bathroom.

01:17:58 Having a phone at hand to call for help is not so bad.

01:18:02 Still concerning the bathrooms, there is generally no suction cup for toilets.

01:18:07 It is to give the impression to the guests who are the first to set foot in this room.

01:18:13 It is a matter of comfort, and it is the priority of any hotel that respects itself.

01:18:18 According to anonymous surveys, the presence of a suction cup for toilets

01:18:22 gives the impression that it could malfunction, and it does not give a very good image.

01:18:27 If the keys to the rooms are magnetic cards,

01:18:30 they should not be stored near your mobile phone or your wallet.

01:18:35 The problem is that the key cards are designed to be reconfigured regularly in a simple and fast way.

01:18:42 So any slightly powerful element, like your phone,

01:18:46 can demagnetize the card so that you will no longer be able to open the door of your room.

01:18:50 The hotel will certainly give you a new card, but it's still annoying.

01:18:54 Some hotels only accept the credit card as a means of payment.

01:18:58 Without a credit card, it is impossible to book a room or pay for services on site.

01:19:04 Booking a room is only the first step of staying at the hotel.

01:19:07 You can take advantage of services such as the mini bar, which will be charged at the end of your stay.

01:19:12 If you don't have enough money to pay the bill on your debit card,

01:19:16 the hotel has no other solution than to start legal proceedings.

01:19:20 Whereas if you pay with a credit card, all additional fees are taken care of by the bank, and everyone is happy.

01:19:28 The arrival and departure times of hotels are not made to bother customers.

01:19:34 They allow guests not to meet.

01:19:37 They also give staff time to clean the room and prepare it for the next guest.

01:19:42 The departure time is generally scheduled between 11 am and noon, for comfort.

01:19:49 You can have your breakfast and get ready quietly at the departure.

01:19:53 In some hotels, there is no power outlet next to the bed.

01:19:58 It's a bit lame, isn't it?

01:20:00 It's all a matter of date. Many hotels were built before the invention of the democratization of mobile phones.

01:20:06 At the time, there was not so much need for power outlets next to the bed.

01:20:11 Many hotels have not yet been updated.

01:20:14 The best way to avoid this problem is to stay in a relatively recent hotel.

01:20:19 When you go to a hotel, staff can recognize you.

01:20:26 It is not uncommon, especially in high-standing hotels, that staff conduct some research on their guests on social networks.

01:20:33 It sounds a bit strange, but it's a good way to know more about them and to be more at ease.

01:20:40 At the registration, you will receive a key that will reprogram the lock and make all other keys unusable.

01:20:48 It is important to be courteous with staff if you want to avoid farces.

01:20:52 The ill-raised guests sometimes have access to two initial keys that will reprogram the lock each time.

01:20:58 It becomes impossible to open the door.

01:21:00 Toothpaste is becoming more and more rare in hotel room bathrooms.

01:21:05 It is too expensive for low-budget hotels because it is considered a medical product.

01:21:11 For luxury hotels, it is the opposite problem.

01:21:14 They can't find a brand of toothpaste that is chic enough to offer it to their clients.

01:21:19 Staff regularly clean the rooms, but don't often disinfect the smallest objects.

01:21:25 Phones and remote controls are the dirtiest objects in hotel rooms.

01:21:30 It is better to sterilize them yourself with disinfectant and a towel.

01:21:35 The safe is not necessarily the best place to store these valuable objects.

01:21:40 Hotel safes are generally code safes and it is very likely that someone knows about them.

01:21:46 Who else can have access to this information?

01:21:49 Over-reservation is a common practice in hotels,

01:21:53 since the average daily number of clients who do not show up is about 10%.

01:21:58 So it is possible that your reservation is not taken into account.

01:22:02 If there are no rooms available when you arrive,

01:22:05 it is not excluded that the hotel pays you another room in a similar structure to the surrounding ones.

01:22:10 People leave everything and anything in hotel rooms.

01:22:14 In Portugal, an employee found a shark that had been abandoned there.

01:22:19 The poor animal was transferred to its natural habitat in complete safety.

01:22:24 Most, if not all, hotels choose carpet covers.

01:22:29 And there is a very good reason for this.

01:22:32 First of all, it is a matter of safety.

01:22:35 There is less chance of slipping and falling on carpet than on parquet or tile.

01:22:40 In addition, it is also economical.

01:22:42 It is easier to change a damaged carpet than to redo the entire floor.

01:22:46 The carpet is also a good way to soundproof a room.

01:22:50 And it's not so bad when you have neighbors.

01:22:52 Too turbulent!

01:22:54 Have you ever wondered what a continental breakfast was and why it is called that?

01:23:00 The name comes from the United Kingdom, which is a set of islands,

01:23:04 and it designates the breakfast that is served in continental Europe.

01:23:08 It can be made up of pastries, different types of tarts, meat, cheese, fruit juice and hot drinks.

01:23:16 Why did we one day decide to add heels to shoes?

01:23:22 The invention of heels dates back to the 10th century,

01:23:25 and the initial goal was to make the footwear more comfortable.

01:23:29 Low heels allowed better fixing the feet in the calves and avoiding slipping.

01:23:34 Several hundred years later, in the 17th century,

01:23:38 heeled shoes became a fashion trend in Europe.

01:23:42 People wore them to show that they had a horse and thus show that they were rich.

01:23:47 Do you remember the "turbo" chewing gums and their particular shape?

01:23:51 This shape was created so that the chewing gum looked like the track of a racing car tire.

01:23:56 10, 9, 8, 7 ...

01:23:59 It's not the space engineers who invented the countdown.

01:24:03 It was created by the Austrian-German-American director Fritz Lang in 1929.

01:24:09 One of his films featured a scene with a countdown.

01:24:13 Then NASA decided to appropriate it.

01:24:16 Take a spoon of spaghetti, the one with big teeth.

01:24:20 Do you see this hole in the middle? Its function is not to swallow the pasta.

01:24:23 It serves to determine the amount of pasta per person.

01:24:26 The amount of dry spaghetti that enters the hole is a standard portion.

01:24:31 You will not need to guess the amount of spaghetti to cook for 3 people.

01:24:36 You just need to measure 3 portions with the help of the spoon.

01:24:40 In a supermarket, you pass in front of a shelf with eggs

01:24:43 and you try to determine which are the best, white or beige.

01:24:48 In reality, there is practically no difference between them.

01:24:52 The color of the eggs depends on the race of the hen.

01:24:55 These hens produce two pigments of different colors.

01:24:58 You can take eggs of any color because their nutritional components are almost the same.

01:25:04 Well, but it does not answer the question of knowing who came first, the beige egg or the white egg.

01:25:10 A small amount of toothpaste, the size of a small weight, is enough to brush your teeth.

01:25:15 But the advertisements mislead you by showing you that you have to cover the entire toothbrush brush.

01:25:21 It's just a marketing trick so you can buy more often.

01:25:25 If planes leave white marks in the blue sky,

01:25:28 it is because of the condensation of carbon dioxide, steam and fuel combustion.

01:25:34 In winter, steam comes out of your mouth.

01:25:37 It's the same principle for planes.

01:25:39 It is always cold at the altitude where the planes fly

01:25:42 and exhaust gases and hot air come out of the turbines.

01:25:46 When they collide with cold air, they create thick lines of steam.

01:25:51 The cooks' coats indicate their rank in the hierarchy, a bit like the heels.

01:25:57 The chef wears the highest coat.

01:25:59 Thanks to this, it is easy to spot him in a kitchen among the staff.

01:26:04 The number of folds on the coat indicates the number of ways the chef knows how to cook the eggs.

01:26:09 Of course, modern cuisines no longer really follow these traditions.

01:26:12 But a coat is always essential.

01:26:15 Thanks to it, not a single hair falls into the food.

01:26:19 Doctors wear scarves for the same reason.

01:26:22 To prevent hair from falling on a patient's forehead during an operation.

01:26:27 There are often cameras in shops, banks and hospitals to monitor everything.

01:26:32 If something happens, you can call the police and the cameras help you solve many problems.

01:26:37 So why aren't there cameras in planes?

01:26:41 The crew keeps order on board, but they can't do anything if something serious happens.

01:26:46 And there is nowhere to run in a plane.

01:26:49 During the flight, the cameras are useless.

01:26:52 And after the flight, the passengers' statements work as well as the cameras.

01:26:57 Finally, the cameras would be an additional cost for the companies.

01:27:01 Almost all hotels have white sheets.

01:27:04 They choose this color specifically to show how high their standards of cleanliness are.

01:27:09 The whiter and more immaculate the sheets, the more luxurious the hotel looks.

01:27:13 It's much easier to see dirt and stains on white laundry.

01:27:17 So it's an additional proof that your room has been cleaned.

01:27:21 You may have wondered why the computer mouse is named that.

01:27:24 In 1968, Douglas Engelbart of Stanford Research Institute presented the computer mouse.

01:27:32 But he didn't remember why it was called that.

01:27:35 The reason was probably that this little wire device looks like a mouse with a tail.

01:27:42 The fuel can form a rainbow in a puddle of water because it can't mix with water.

01:27:47 It forms a thin membrane on top, and when the light reflects both on the fuel and on the water, you get a rainbow.

01:27:55 Magnets are often in the shape of a horse's iron because it increases their magnetic force.

01:28:00 Colors are also important.

01:28:02 The blue part indicates the South Pole, the red part the North Pole.

01:28:06 Both poles work simultaneously and increase the attraction force.

01:28:11 The sign "Do not disturb" on the door of your hotel room is not an obligation, but just a suggestion.

01:28:18 The room attendants and the staff are allowed to go there if they suspect that something is wrong,

01:28:23 especially if you don't remove the sign for 24 hours.

01:28:27 Why do the clock hands move to the right?

01:28:30 The sun is the main reason.

01:28:33 In ancient times, when people invented the solar dial,

01:28:36 the shadow of the sun moved to the right in the northern hemisphere and to the left in the southern hemisphere.

01:28:42 However, mechanical clocks were invented for the first time in the northern hemisphere,

01:28:47 or as we say today, in the direction of the needles of a watch.

01:28:51 If diamonds are cut in such a symmetrical way, it is to show you their brilliance.

01:28:56 At first, precious stones are not so regular.

01:28:59 They go through several stages of size and then become pieces of ornament.

01:29:04 Most of these pieces have a round shape with slightly pointed corners,

01:29:09 because it is in this shape that diamonds shine the most.

01:29:12 Why are there two or three holes in a power outlet?

01:29:16 The left hole is neutral, the right hole is hot, and the possible hole below is the ground.

01:29:22 Electricity must flow in a loop.

01:29:25 The current comes out of the hot hole, goes through the charger of your phone, for example,

01:29:29 then enters through the neutral hole.

01:29:31 Have you ever wondered what the small pocket of your jeans was for?

01:29:35 In the past, people wore watchcases and this small pocket was designed for this purpose.

01:29:41 Today, no one wears such a watch anymore, but the pocket has remained.

01:29:45 You can keep a small object there, such as an alliance, for example.

01:29:49 The socket stick has two holes for a good reason.

01:29:52 When you put the stick in hot syrup, the liquid flows through these holes.

01:29:56 This helps to keep the socket firmly on the stick when it is completely solidified.

01:30:01 The cap of the pen also has two holes.

01:30:04 They were created to prevent you from choking if you accidentally swallow the cap.

01:30:09 It's reassuring, but still avoids me from choking the cap.

01:30:13 Why did people start wearing ties?

01:30:16 This goes back to 17th century Europe, where the tie was originally used to tighten the collar of the shirt,

01:30:22 which protected the soldiers from the cold wind blowing on their necks.

01:30:26 But King Louis XVIII liked this clothing element so much

01:30:30 that he made it an essential accessory for royal gatherings.

01:30:34 Why are Chinese chopsticks tied together?

01:30:38 If they are disposable, they must be connected by a small piece of wood

01:30:42 to prove that no one has used them before you.

01:30:46 The small pieces of fabric stored in new clothes are not repair patches.

01:30:51 They are test samples for washing in the machine.

01:30:54 You can put this piece of fabric in your washing machine and see what happens to it.

01:30:58 If everything goes well, you can wash the clothes safely.

01:31:02 Why are the festive goblets often red?

01:31:05 Because it helps you quickly find your drink on the table,

01:31:09 among the aperitif cakes and bottles.

01:31:11 If there are many others, you can write your first name on them.

01:31:15 In addition, red is considered a color that provokes action.

01:31:19 Psychologically, it's like if your goblet said, "Drink me!"

01:31:23 It is thought that yellow taxis originated in Italy in the 15th century.

01:31:28 A postman used yellow chopsticks to distribute the mail

01:31:32 so that everyone recognized them.

01:31:35 The types of dough have different shapes

01:31:38 because each shape is suitable for a particular sauce.

01:31:41 For example, fine and smooth doughs are perfect for sauces and light ingredients,

01:31:46 while thick and wrinkled doughs, like penne,

01:31:50 are ideal for thicker sauces and vegetable stews.

01:31:53 Why are the lab coats white, blue or green?

01:31:57 Before, the medical staff only wore white clothes

01:32:01 because this color was considered a symbol of cleanliness and sterility.

01:32:05 Then, at the beginning of the 20th century, they started using green

01:32:09 because this color is more resistant to the eye of the doctor.

01:32:12 When a surgeon sees red for a long time during the operation,

01:32:16 his eyes reduce their sensitivity to this color.

01:32:19 The shades of red mix and doctors can no longer see the nuances of the human body clearly.

01:32:24 Conversely, blue or green areas help to refresh their vision.

01:32:29 The eyes rest for a second, then return to the red color again.

01:32:34 If a doctor looks at a white glove during the operation,

01:32:38 small green spots can appear in his eyes.

01:32:41 You can check for yourself.

01:32:43 Look at something red for a few minutes,

01:32:46 then turn your gaze to a sheet of white paper.

01:32:49 You will see these spots of a greenish hue.

01:32:51 Doctors therefore wear blue blouses to avoid being distracted.

01:32:55 However, different hospitals may have different rules.

01:32:58 Blouses can be of different colors depending on the hierarchy.

01:33:02 This is necessary to distinguish a doctor from a nurse or a nurse.

01:33:06 In any case, patients must always wear this blouse open on the back.
