Air travel has its own strict and mysterious rules.

Keep your window shades open.

Trade tables put away seat in the upright position and don't try to tinkle before takeoff.

Wait, what's that last one again?

Wow, Why can't you use the bathroom before takeoff and what'll happen?

If you try?

Well, let's start at the head.

You arrive at the airport way too early and start wandering around, trying to pass the time.

At one point, you end up at an airport coffee shop, sipping on a large cappuccino.

Easy.

Now you're going to regret that decision later.

Ah, well, what's done is done.

Sure enough, About 1/2 hour later, you're standing in line about the board, the plane, and your body insists on getting rid of all of that liquid you've so recklessly gulped down.

Told you so.

Whatever you think, I'll head to the loo as soon as I find my seat.

And so you reach your seat, stuff your carry on in the overhead bin and look back on Lee to notice the signs.

Above all, the onboard toilets are glowing red.

Wait, There must be some mistake.

We're still on the ground they probably just forgot to unlock him.

But before you can inform a flight attendant about their mistake, the aisle is already filling with other passengers and you have to sit down.

Why not make yourself comfortable while waiting without thinking twice, you recline your seat back and relax into it.

In no time you see a flight attendant rushing towards you.

Please return your seat to the upright position.

Come on.

What's wrong with getting that bit of comfort you paid for?

Well, plenty of things.

Right now you're recline.

Seat is preventing passengers in the row behind you from getting into their seats.

Plus, if something goes wrong and there's an evacuation, you're tilted seat won't let them get out of their places as fast as possible.

And if you keep your chair back during landing, your neighbor to the rear can hit their head on your seat back.

Oh, it's for your safety, too.

If you're lounging in a reclined position during a crash landing, your head will travel further since it collides with the seat back in the front of you Along the way, it will generate more force, which can lead to a serious neck or head injury.

And last but not least, the passenger behind you will simply hate your guts for the duration of the trip.

Okay, it was worth a try.

You hear the engine startup, you decide to scroll through your social media feed?

Could you please put your phone in airplane mode or switch it off completely?

We're about to taxi to the runway.

It's the same attendant again.

This is not your day.

To be honest, nothing dramatic will happen if you use your phone while the plane is taking off or landing.

But what if at least 20 other passengers join you?

Pilots say in this situation they can get false readings on their instruments.

For example, inaccurate information that the plane is higher than it is.

This can easily lead to a crash.

So no phone for you.

Better safe than sorry.

Fine.

What about my laptop?

No Internet promise.

You take the thing out of its case, put your earphones in and get ready to watch your show.

Previously downloaded episodes.

Of course, that's when your neighbor starts making some sort of hand signals like you need to take your earphone out.

I wouldn't do that if I were you, you're supposed to keep your laptop in its bag and story in the space in front of you for a reason.

If something goes wrong during or right after takeoff, Ah, laptop can fly out of your hands at race car speeds and getting hit by what's now nothing more than an overpriced boomerang.

Could really do someone in no problem, laptops going away.

The plane finally starts moving and you see that.

Fasten your seat belt, sign overhead.

But you haven't gone to the bathroom yet.

Hurry.

You stand up and head for the toilet on Lee to be intercepted by Nurse Ratchet.

I mean the flight attendant.

Then you feel the plane.

Come to a sudden stop.

Could you return to your seat, Sit down and fasten your seat belt, please.

She clearly looks like she's losing her patients with you.

Confused, you go back to your spot.

Could this no bathroom before takeoff?

Business.

Have something to do with how airplane toilets work.

For those, you can't have a conventional water filled bowl.

Otherwise, any slight turbulence would make the water splash out onboard.

Camo DS are vacuum based.

They really suck when you press the flush button off valve opens, and the vacuum sends everything from the bull into a special tank.

That vacuum, in turn, is created thanks to the immense difference in air pressure that's high up in the sky.

The high pressure inside the cabin pushes wets ever in the bull down and out to where the pressure is lower.

Ah, that must explain it.

No pressure difference on the ground.

No flush and not quite.

There's a generator in there that can create the vacuum itself.

When the plane isn't at a high enough altitude, so do they not want you to flush the toilet before the take off to save energy?

Well, consider this just a taxi and take off.

A jumbo jet uses enough energy to power about four million laptops.

A few passengers flushing the toilet during taxing won't change much.

The whole bathroom ban mostly comes down to safety.

Ah, plane can't taxi if a single person is out of their seat and not wearing a safety belt.

And for obvious reasons, toilets don't have any seat belts.

It's so that a wandering passenger doesn't get knocked down or fall into something in the tiny space of a bathroom.

There are plenty of places to hit your head.

That glass mirror looks especially scary.

That's why if you insist on using the John before takeoff, the plane is likely to stop moving altogether and everyone on board will be waiting for you to finish your business.

And such delays have very costly consequences.

If a plane stops taxing, it'll lose its place in line and have to wait for others that are scheduled before it can take off.

It doesn't matter what airline you fly through.

They all have this rule.

There have even been cases where passengers were removed from their flights because they insisted on going to the bathroom when the plane was already traveling toward the runway.

The only loophole you can use is a tarmac delay.

If it happens, the cabin crew must let you use the toilet if you need to.

But the moment the plane enters a taxi way, you have to be buckled into your seat.

Finally, the plane takes off, reaches his cruising altitude and the fasten your seat belt signs go off.

You can finally make that long awaited bathroom trip after returning to your seat.

You notice that the cabin has gotten chilly.

Time to turn off that bothersome air vent over your seat your nose.

A knowledgeable neighbor starts spilling.

More advice.

You should probably keep that on.

The flow coming from the vent blows away airborne germs that are just waiting to enter your personal bubble.

It's better to put on some extra clothes than to turn that vent off.

By the way, if you often get cold on a plane, choose a seat in the back.

The airflow goes from the front to the end of the cabin when the cool air reaches the tail.

It's not that cold anymore, but if you want the air you breathe to be as fresh as possible.

Choose a seat in the front Now, if you're a nervous flier book a morning flight later, the ground gets heated and it causes bump your air.

Plus thunderstorms are more likely in the afternoon.

And if you don't want to feel the turbulence so strongly, sit near or over the wing.

Imagine your plane like a giant seesaw seated in the back.

You'll have the bumpy ist ride, but the plane's central part doesn't move as much.

Pilots don't care too much about turbulence, though it's pretty much harmless.

What they are worried about is updrafts, air moving upward because of a storm or some other weather conditions.

Being on a plane that's flying into a huge updraft feels like hitting a giant speed bump at hundreds of miles per hour.

Everything flies up into the air and then suddenly drops down with a boom.

And if you have a window seat, try not to sleep against the pain.

You can't even imagine how many people have had their heads pressed against those windows before.

In other words, you're laying your head on a big glass bed of germs.

It's better to grab a neck pillow.

Now you're all set.

Uh, thanks, Belle.
