- [Narrator] Air travel is truly amazing. Because of it, it's
easier than ever before to see the world and all
its incredible cultures. But just because you're on a plane doesn't mean there aren't rules. And if you break them, there
can be dire consequences. So, from turning off airplane mode to climbing into the
overhead compartments, get ready for some things you
should absolutely never do on an airplane. (upbeat music) Spoil-shorts. My last vacation got off to a poor start. I'd only just boarded the plane when the flight attendant
told me I had to take off my Batman costume or leave. It turns out airlines have dress codes. What's more, different
airlines have different codes. And these can change depending on the country you're flying to. Jeez, confusing or what. See, some countries, like Indonesia, are predominantly Muslim, and as such dress more
conservatively than other places. So if you're flying there,
it's polite to cover up before getting on the plane. But it's worth looking
into clothing guidelines before getting on any flight. Dirty, torn, or revealing
clothes can breach codes and get you kicked off the plane, which makes sense, but sometimes so can things as benign as flip flops. Seriously. Back in July 2021, Turkish
bodybuilder, Deniz Saypinar, made headlines when she tried to board an American Airlines flight to Miami. Apparently, her shorts were too short, so she was duct taped to one
of the chairs and left there. (audience gasps) Okay, not really. She was just denied entry onto the plane. Somebody actually was duct taped to a seat for a very different reason, but you'll have to stick
around to find out about that. Anyway, after being
refused onto the plane, Saypinar was understandably upset and took to social media
to vent her frustrations. According to the bodybuilder, she wasn't dressed offensively at all, and the whole thing was
an attack on her freedoms as a woman. Hmm, what do you think? Were the airline staff right or has Saypinar got a good point? Would a man have been refused entry if he was wearing the same outfit? Let me know your thoughts
down in the comments. No signal, no problem. You've probably heard the horror stories about what'll happen if you don't put your cell
phone on airplane mode during a flight. Planes will fall from the sky. Chaos will ensue. Well, you'll be glad to
hear that's not quite true, but you should still turn it on. When you do, it blocks the phone from searching for signal. Some pieces of pilot's equipment use the same radio
frequencies as cell phones and tablets to function. So when your phone looks for a signal, it can intervene and disrupt them. Think of it like tuning an
old-school analog radio. When two stations are
on a similar frequency, they can interfere with one another and make the signal unclear. It's the same thing here. And pilots need this equipment to tell how far they are from the ground during take-off and landing,
pretty important stuff. Indeed, back in January 2017, the pilots of a Boeing 737
lost all of their map displays and computers while they were in flight. Whoa. Miraculously, they managed
to get the situation under control and avoid crashing, but investigators reckon
someone's cellphone signal could've been to blame. As scary as this whole thing is, no planes have ever actually crashed from cell phone interference,
at least not yet. However, it's still a good idea to text your mom after
the flight, not during. (PA system beeping) Hello, this is your captain speaking. Don't even think about putting that phone on airplane mode right now though. Hit those like and
subscribe buttons instead. That way, when we land, you'll never miss another amazing video like this one. All done? Okay, enjoy the rest of your journey. Phantom Flyer. Now, I've been on quite
a few flights in my life, and they've all been pretty boring. American actor, Emerson Collins, definitely can't say the same though. In September 2022, Collins
was on board a plane when suddenly he started hearing this. (prankster groaning) (prankster groaning) And it didn't stop there. The strange, guttural noises
carried on for seemingly ages. And at one point, a flight attendant had to announce an apology. - [Flight Attendant] Ladies and gentleman, we realize there's an
extremely irritating sound coming over the public announcement. The flight deck is trying to troubleshoot, trying to turn it off, so
please be patient with us. We know it's a very odd and- - [Narrator] (laughs) So
what the heck is going on? Well, this wasn't the work
of some high-flying ghost. Somebody had apparently hacked
into the plane's PA system and was pranking everyone on board. How they did this, nobody's sure. But the weird noises went
on for the entire flight. (prankster groaning) If you got caught doing this,
I'm sure you could experience some serious legal repercussions. But as far as I'm aware,
nobody did get caught. And the mystery remains
unsolved to this day. So the main consequence
was just annoying the hell out of the captain and cabin crew. Hey, I'm not complaining. I just got a new ringtone. (prankster groaning) Filthy flights. I think we can all agree
that littering is bad. But people who leave their
litter festering on planes? Well, they're the worst. Flight attendants are often only paid for their time in the air. So if there's any trash left
on the plane after landing, they have the disgusting
task of cleaning it without even getting any money. And I really do mean disgusting. As well as old food, one
attendant reported finding, brace yourself, countless dirty diapers and soiled underwear stuffed
into the seat pockets. Oh man. Diapers are bad enough, but
actual adults' underwear? Come on. And it gets even worse. Other attendants have
found used catheters, toilet paper, and even bottles of pee. How did they even, actually,
I don't wanna know. Just, please, for the
sanity of the poor people charged with cleaning up this mess, don't leave trash on the planes. And never, ever put your
food in the seat pockets. You have no idea what horrors have been in there before. Peculiar passengers. Now, don't get me wrong. I love pets. But I wouldn't wanna take
one on a plane with me. Even so, some airlines allow
all sorts of animals on board, as long as they're well behaved. Others only allow service
animals like guide dogs. But to get around this,
people began bringing their non-service pets on board and claiming they were service animals so that the critters
could travel for free. We're talking guide horses,
peacocks, and even pigs. And these so-called service animals would often run amok, pooping everywhere, being noisy, and generally causing chaos. Jeez. Because of this, a new law was passed banning all service animals
other than dogs from flying, but some people argue this is unfair on those who genuinely rely on them. Regardless, there are far
worse things you can bring onto a plane than a peacock. Yep, back in 2012, a man
caught a wild Egyptian Cobra and shoved it in his hand luggage to bring back to his
reptile shop in Kuwait. Somehow, he managed to
get it onto the plane, but once he was seated, controlling the restless
reptile proved difficult. Egyptian cobras are very
aggressive and super venomous. And after a short struggle, it bit him and escaped into the cabin. It was pandemonium. From what I can tell, the man survived despite his stupidity. But in the ensuing panic,
the plane had to make an emergency landing so the
snake could be dealt with. And there I was thinking
"Snakes on a Plane" was silly. A few years later, in 2016, something arguably even
more terrifying happened. One passenger on a flight to Montreal was relaxing on her iPad when
she suddenly felt a tickle on her leg. Looking down, she realized with a pang it was a great big tarantula. She smacked it away from her,
but it wasn't the only one. Somebody had brought two
of the spiders on board to bring home as pets. So the rest of the flight,
passengers were forced to stand on their seats to
avoid the creepy crawlies. Am I the only one getting itchy? The forbidden orders. I don't know about you, but
every time I'm on a plane, it takes about five minutes for my mouth to feel as dry as the Sahara Desert. But when that all-important
refreshment trolley comes round, think twice before you make your order. More specifically, don't
choose tea or coffee. Water tanks on planes are
often old and full of bacteria. And tea, coffee, and even ice
will probably utilize them, meaning your tea could come
with a side of illness. Gross. Sticking to bottled
drinks is much less risky, despite the extortionate prices. If you're old enough to
drink alcohol though, there's even more to watch out for. When you're 12,000 feet high in the air, there's far less oxygen
than there is on the ground. The pressurized cabin
ensures you can breathe, but you're still more likely to feel lightheaded and nauseous. If you combine that with
a good slosh of booze, it can get out of hand fast. In June 2021, a passenger got so drunk he tried to bite a
member of the cabin crew and had to be locked inside
the airplane washroom. What? I mean, I get a little
peckish after a few beers, but a kebab usually does the trick. Regardless, the man was
sentenced to 20 months in jail for both the assault and
his intoxicated state. Because even if he hadn't bit anyone, he still would've been breaking the law. It's a criminal offense
to be drunk on a plane. And after that story, I
can definitely see why. Badderies. How would you react if
I told you your phone could erupt into flames any time you take it on a plane with you? At least, if it has a lithium battery, and it probably does. Lithium batteries are inside
all sorts of everyday devices, including phones, laptops, and cameras. If you bring any of
these on board with you, airlines will highly encourage you and sometimes require you to
keep them in your hand luggage, not in your main luggage. Okay, but why? Well, lithium batteries
are extremely sensitive to high temperatures, as well
as being incredibly flammable. Not a great combo. They're highly unlikely
to randomly combust, but malfunctions do sometimes happen. And because planes have drier air than the outside atmosphere, if anything does catch fire,
it'll spread much faster. Now, if a fire takes hold
in the cabin, it's bad. Unless you put it out fast, smoke could rapidly
fill the enclosed space, whilst the fire itself
damages the aircraft and potentially burns the passengers. But at least the crew have
a chance to deal with it before it gets out of hand. Back in 2018, a power pack overheated and caught fire in the
overhead compartment on one flight to Shanghai. Because it was in someone's hand luggage, staff quickly threw water
on it and put it out. If that same fire had
happened in the hold though, well, nobody could've reached it and it would've got a whole lot worse. So, yeah, don't put your
phone in your main luggage unless it's safely turned off. The only fire that should
be allowed on a flight is my rap mixtape. Word. Flying flu. My grandma always used to tell me, "A bit of dirt will do
you good, young man." And maybe she was right, to a degree. But I don't think that
saying applies to airplanes. Plane cabins are compact, enclosed spaces, with loads of people crammed into them, and a limited supply
of air in circulation, air that everybody is breathing in and out and passing to one another. They do have filter systems
to get rid of airborne germs, but they're not 100% efficient. There are air vents above every seat too. However, if you're anything like me, you turn those straight off
so it doesn't get too cold. Well, you shouldn't. By leaving the vent open,
fresh air is channeled in from outside, increasing air flow, pushing bacteria out of your vicinity, kind of like a little force field. So, if you get cold, trust me,
instead of closing the vent, just slip on a sweater. Vents open. Forcefield up, Mr. Sulu. It's germin' time. Alright, so we know flight attendants have found some truly gross
things on board planes. And we also know that
germs can run rampant within the enclosed space of the cabin. With that in mind, would
you take your socks off and walk around barefoot? I mean, the floors have
probably seen vomit, poop, and all sorts of unmentionable goo. You'd have to be crazy, right? Well, apparently some
people are that crazy. And even worse, they
shove their dirty feet in other people's faces. I can't think of anything
grosser than turning round and seeing these toed monstrosities poking through beside me. Like, seriously, doing
that isn't just nasty, it's also super unhygienic. But not that barefoot warriors are the only germ-spreaders
you might encounter. Oh no. One unfortunate vacationer
found themselves sat behind this. Why, is all I wanna know. I'd be tempted to give
that hair a hard tug if it didn't look so dirty. Though it's probably still cleaner than the in-flight blankets
airlines sometimes provide. Apparently, there's rarely enough time to clean all of them between flights, so they're often reused. Yuck. No matter how much hand
sanitizer you lather on, if you've got a snotty,
drool-covered blanket draped over you, you're still gonna have a butt-ton of germs to deal with. And if staff don't have
time to clean the blankets, do you think they had
time to clean the windows? Well, I sure don't. So avoid leaning your head on those too. They might not look dirty,
but bacteria are microscopic. And while you snooze against the window, they could be multiplying
all over your face. Alright, you're probably sick of hearing about gross stuff now, but I've saved the most
outrageous for last. This woman was caught drying her underwear with the air vents. (narrator sighs) Faith in humanity officially lost. Overhead beds. I don't know about you,
but my hand luggage is always overflowing with Twinkies. So, when I pop it into the
overhead lockers for the flight, I can easily stand up and
grab a few when I get peckish. I'd get the shock of my life though if I stood up and found
myself face-to-face with a person crouching in there. Yup, it should be obvious
that the overhead bins are for luggage, not humans. Surprisingly, however, many people still try
to clamber into them. Even more surprisingly,
it's flight attendants that are the biggest culprits. Sometimes they do it as some kind of newbie initiation ceremony, other times just for the gram, which is weird but relatively harmless. On one Southwest Airlines
flight back in 2019, an attendant even sat
in an overhead locker and greeted passengers as they boarded. Sometimes however it's not so harmless. In 2011, a Virgin Blue employee was fired after he picked up a passenger's toddler and put them in one of
the overhead lockers. Yep, you heard that right. Apparently, the attendant
was just joining in with the family's game of hide and seek, but the mother and father of the child definitely didn't see it that way. So yeah. I never thought I'd say
this, but don't ever put kids in baggage compartments, alright? Cool. Under pressure. So you've been at the airport for hours, queuing, checking, and
going through customs, and you're exhausted. When you finally get on the plane, all you wanna do is go to sleep, right? I know I do. But hold up, you don't
really wanna do that, at least not straightaway. You see, when a plane takes off, the air pressure inside
the cabin changes rapidly. This makes the pressure outside your ears different to the pressure
inside, and creates a vacuum, preventing your eardrums
from vibrating normally. If you've ever experienced it, you'll know that uncomfortable,
blocked sensation. The good news is, you can easily fix it by yawning or swallowing. These actions open the
eustachian tube in your ears, which is the thing that
regulates pressure, allowing air in and easing the pressure. Simple. If you're asleep however,
you can't do this. And if you leave the
pressure to build and build, it can get really bad really fast. I'm talking dizziness, nosebleeds, and even permanent hearing loss. Yikes. So, yeah, try to keep
those tired eyes open until the plane is safely in the sky, then you can sleep as much as you want. Just make sure you wake up
in time for the landing, because the air pressure
shifts again when you descend. Jeez. Contact chaos. What's dryer than eating
a cracker in the desert? Clue, the answer's not my
incredible sense of humor. It's actually an aircraft cabin. Because there are so many
people in a commercial plane, fresh air needs to be pumped in or all the passengers would run
out of oxygen and suffocate. But when you're 30,000 feet high, there's hardly any
moisture in the atmosphere, so any air that's brought in is super dry. This isn't just uncomfortable, it could be legitimately dangerous, at least if you wear contact lenses. You see, the dry air dehydrates your eyes, which in most cases just
makes them feel uncomfortable. But it can also cause the
lenses to tighten around them and rip microscopic
tears into your cornea, that is the eye's outer layer. Ouch. So if you need to wear
your contacts on board, make sure you bring eyedrops
to relieve any dryness. And never sleep with them in. You could wake up feeling like
someone's plunged hot coals into your eye sockets. Though with some of the inflight
movies they choose to show, maybe that wouldn't be
such a bad alternative. Standing no-vation. I can't stand people who
clap when the plane lands. Do they also clap when their
food arrives at a restaurant or when the mail turns up? (scoffs) I don't think so. Still, I'd prefer clapping
over a load of people jumping out of their seats. The seatbelt light isn't
just there to look pretty. When it's on, don't stand up. If you're mid-flight, the
pilot's probably activated it because they reckon you're
about to hit some turbulence, you know, that pant-wettingly scary thing when it feels like the
plane's about to crash. It's not, it's just
colliding with air currents. But if you're standing up, you could get thrown to the floor. Even when you're not
going through turbulence and it feels like you're
hardly moving at all, you could actually be racing forward at nearly 600 miles per hour. So if the pilot has to use
the brakes for any reason, well, you guessed it. You'll be sent flying. Just don't do it. And please, don't clap
when you land either. I will steal your complimentary
in-flight peanuts. Plane potato. Plane journeys can be
long and deadly boring, so it's tempting to
sleep for the whole ride or maybe watch the entire
"Lord of the Rings" trilogy, but neither of those are great ideas. If you stay seated for hours on end without any kind of movement, you could get yourself in big trouble. That's because sitting still
for long periods of time can disrupt the blood flow in your body, slowing it down and sometimes
blocking it entirely. You've probably had
pins and needles before, well, it's kind of like that
except it can get a lot worse. If you don't move around, blood
cells might clump together and cause clots in your legs, leading to painful swelling. This is called deep vein
thrombosis and can be excruciating. In the worst cases, you might
even get a clot in your lungs, which is really bad news and
could be life-threatening. And you only need to be
motionless for four measly hours to be at risk. So next time you fly, remember to get up and have a little wiggle
every now and then. Just not when the seatbelt
sign's on, alright? Bad taste. As an all-knowledgeable expert comedian, I know exactly how to get a laugh. (imitates flatulence) Absolutely classic. I'm a comedy genius. Some people aren't so
innately hilarious though and choose to joke about stuff
like terrorism and bombings. Seriously. As well as being in terrible taste, jokes about any kind of violence can carry serious consequences
if you're at an airport or on the plane itself. Even if they're sure you're joking, airport staff must take any possible threat of
terrorism seriously. And sport stars aren't
exempt from this rule either. Back in April 2018, then
Green Bay Packers receiver, Trevor Davis, was checking in for a flight at Los Angeles International Airport when a member of staff asked
him if he'd got any contraband. Davis jokingly said yes
and then asked his friend if he packed the explosives. Well, safe to say the
joke didn't go down well. He was arrested on the spot and charged with making
a false bomb threat. The charges were eventually dropped, but the tale still serves as a warning. Stick to making fart jokes. Flight attendants love those, trust me. I'ma head out. Okay, so when it comes to things you should never do on airplanes, there's one so glaringly obvious you'd think nobody would
ever actually try to do it. Any guesses what I'm talking about? If you said opening the plane
door while it's in the air, hey, you're correct. But believe it or not, someone
did try to do just that as recently as July 2021. Yep. Whilst on an American Airlines
jet to North Carolina, a woman suddenly got out of her seat and started attacking
the flight attendants before running to the plane's front door and desperately trying to tug it open. Luckily, members of the
cabin crew leapt onto her and managed to get her off
before anything drastic happened. But worried she'd try and do it again, they decided to duct tape her to her seat for the rest of the flight. Jeez. It turns out the woman was having some kind of mental breakdown, which is actually pretty sad. But damn, being on that plane would've been one of the
most terrifying things ever. In reality, even if the woman had overpowered the flight attendants, the plane would've been safe. Despite what you may
have seen in Hollywood, it's impossible for someone
to open a plane door while it's flying. A plane's interior is pressurized, meaning at high altitudes, there's about 1,100 pounds of pressure pushing against each
square foot of the door. And because they open inwards, you'd have to overcome
this immense pressure to get the door open, something no human being
is strong enough to do. So that's nice to know, I guess. As you saw though, just
because it's impossible doesn't mean you'll get
away with trying to do it. As well as potentially
getting duck taped to a chair, you could also face serious
legal action on landing. Hmm, sounds like a
pretty sticky situation. And on that incredibly funny
pun, our flight's at its end. Which of those shocked you the most? And do you have any crazy
airplane stories to share? - [Pilot] Well, we've just
landed in the comments section, so let me know down below. And thanks for watching. (lighthearted music)
