At first, this might look adorable and harmless. However, if it goes on throughout the entire flight, it becomes a whole different story.

Most people would find this irritating. Good thing that this woman has a good sense of humor. She’s seeing the funny side of it!

If you have a terrifying fear of birds, this is the last person you’d want to sit next to. Flying next to a bird is still uncomfortable- even if it’s wearing a really cool bird diaper.

You’re not really supposed to pop your pimples because it puts you at risk of infection and scarring. Apparently, this woman didn’t get the warning. She’s been popping zits for most of the flight.

There’s nothing wrong with getting dreadlocks as long as you keep them to yourself. If you’re in a flight, make sure your hair doesn’t get to the next seat.

If you don’t want your hair on your own face, you certainly wouldn’t want it to be on another person’s face. Just look at this guy’s expression- he’s so revolted at the lady.

This is a photo of a couple breaking up during a flight. Clearly, it’s not the best way or place to dump someone. And if you’re flying for long hours, the seat next to them is not the best place to be in, too.

If you don’t have headphones, you either turn it down or turn it off. For this guy, it seems that no rules apply.

It’s totally fine to eat cheese puffs in a flight. Just make sure that the orange residues don’t go all over the place. Oh, and make sure to close your mouth, too.

Not having a big leg room can be a problem if you have long legs. The solution, however, is not to put them up.

There’s a certain thing as personal boundary and it exists even when you’re in a plane. This man, however, decided to put his second laptop on his seatmate’s table.

When you’re flying for a couple of hours, you should try your best to make yourself as comfortable as possible. Apparently, this guy had no problem with that.

All that mess isn’t just annoying for the person in the next seat. It’s a big headache for the person who’s responsible for cleaning the plane.

The pressure inside the plane can affect your hearing, but it’s not an excuse to leave those things in the plane. It’s gross and totally a bad habit.

The plane is not the right place to dry your socks. Period.

This person is either a fan of Chucky or he’s just trying to make everyone near him anxious. Well, he’s doing a great job so far.

This woman made sure that her plush hamburger has a comfortable spot during the flight. She even put its seat belt on.

It’s totally unacceptable to put your feet like that. And it’s improper to keep your feet that dirty, particularly when you’ll be in a flight.

There are so many things wrong in this picture- the frizzy hair, the way it’s left like that, and how it’s blocking the screen. The way that woman seem to don’t care is the most horrifying of all.

Apparently, this turkey was supposed to be a therapy pet. Whether or not that’s the case, we can all agree on one thing- it looks creepy.

It’s perfectly fine if you want to take your shoes off during the flight. Just make sure you’re not letting them touch the feet of the passenger sitting in front of you.

It’s wrong to block another passenger’s view. It’s more wrong to hold that knife that way.

If you’re going to eat pistachio, dispose the shells properly. The plane isn’t your garbage can.

Looks like someone forgot to bring her kids’ art book. Despite that, the kid still managed to be busy throughout the flight.

It’s easy to get bored when you’re flying for hours. Signing seats, however, isn’t an acceptable way to let time fly.

See that man wearing an orange shirt? His expression is enough for this photo.

It’s hard to decide which is more disturbing in this photo: the woman in her underwear or the fact that she doesn’t mind it.

Yes, we know that’s not soda. What we don’t know is why that person decided to take a piss in that bottle.

This one is an eyesore. The pants, the underwear, and the mess around him- everything looks wrong.

Before you leave the plane, you’re supposed to look at your seat first to make sure you didn’t forget anything. If the person sitting on this spot did that, he would probably realized that he’s missing his underwear.

We all have different things that make us fall asleep faster. In the case of this man, it’s going shirtless. Good thing that the women next to him are all sleeping or else, they could have freaked out.

Someone felt too entitled that he had to put both of his feet in that spot. For a flight that lasts for hours, this is a nightmare.

A mom’s got to do what she’s got to do to keep her child comfortable during a flight. That includes changing diapers on the plane’s floor.

We all have our own ways of keeping ourselves busy during a flight. This man has an odd choice.

He’s probably just waiting for his friend to give him a high-five. Otherwise, why would he put his foot like that?

So, this woman decided to do her nails during her flight. Although it’s not illegal, it’s clearly a rude thing to do.

This woman is either showing off her long nails or that fancy ring and she’s making sure that the person behind her notices. What an awful way to brag!

Just when flight attendants think they’ve seen it all, this plastic bag appeared after a flight. No need to guess what that yellow liquid is.

Potty training is important for growing kids. However, that doesn’t mean that potty training and leaving the mess for the attendant to clean is acceptable.

Parents shouldn’t really be doing this. It’s unsafe and surely gross. That floor could be harboring thousands of bacteria that can compromise the baby’s health.

When you’re trying to get fit, you take every chance you get to work out. For this man, the list includes plane rides.

Apart from the turkey, a duck made it to this list, too. We’re wondering if it’s a therapy pet, too.

How can you sleep if you’re sitting next to someone who snores? The answer involves earplugs.

The photos of people putting their feet up in planes seem endless. Even this poor girl can’t stand it anymore.

Poor fellow had to endure the rest of his flight sitting that way. He didn’t even get to read the paper without his forehead touching the other passenger’s seat.

Apparently, humans aren’t the only annoying creatures on the plane. Spiders can ruin your trip, too.

Good thing that the passenger is more into books than watching movies. Otherwise, he could have been tempted to chop off that hair.

To do the laundry or go on with the flight? This passenger had a hard time choosing so she did her laundry during her flight.

Before your flight and before leaving your home, make sure you’re done with your personal grooming. Otherwise, you might end up hurting someone in the airplane with your flying fingernails.

A sprained ankle needs to be elevated most of the time to encourage healing and reduce swelling. If you’re in a plane, however, it’s best to keep your foot on the floor.

This man wanted an orange juice. After being informed that the crew is only serving apple juice, he refused to sit down.

There are two things that you’ll find bothering in this photo. One is the pair of feet brushing down the back of another passenger’s feet or this feet’s intense dryness. Make sure to moisturize before getting on a plane!

This woman seemed to have mastered the art of annoying co-passengers. From the way she’s eating her food to the way she positioned her feet, it’s hard to find something to love about this photo.

During the first few seconds, you’ll find a baby’s stare adorable. The longer it lasts, the creepier it becomes.

These ladies look like they are enjoying the flight. The passengers behind them? Not so much.

Good thing that this man chose to wear decent socks. At least, there’s still something positive about his foot on that seat.

This one is quite infuriating both for the person who’ll have to clean it and the person who’ll be occupying the seat. It’s’ clearly not the best spot to spit sunflower seeds.

This passenger didn’t feel content with his feet up in the air. He had to stretch and switch feet multiple times.

This one is beyond disgusting. How could anyone use a condom during a flight and how could anyone leave it like that?

It’s hard to understand how some people could leave their garbage anywhere. We get that flying for several hours can be stressful, but that’s not an excuse not to behave properly.
