Keeping your legs covered on the plane isn't the only advice Cimato had for his followers.

He also warned flight passengers to avoid falling asleep or leaning their heads on the window. "You're not the only one who has done that, and you don't know how many people have wiped their hands or other things all over the window," Cimato said.

And there's one part of the plane he says to never touch with your bare hands.

In a July 27 TikTok that went viral, flight attendant Tommy Cimato detailed a handful of things people should never do on a plane, one of them being wear shorts. Don't "wear shorts while you're on an airplane," warned Cimato. He pointed out that you don't know how many people have wiped their hands on the seat or what has touched it. "You never know how clean it's going to be, so if you have pants, you're going to have fewer germs," he explained.

Deciding what to wear on the airplane is a decision you'll have to live with for hours. Finding the sweet spot between being comfortable but not looking like you're wearing pajamas when you check in to your hotel can be a challenge. There's also the additional conundrum of finding a way to dress appropriately for the weather at the location you're taking off from, while also being dressed comfortably for the temperature at the place you're flying into. But if you've got one last summer vacation coming up, there's one thing you should absolutely not wear. A flight attendant recently urged passengers to avoid wearing one particular article of clothing on a plane. Read on to find out what it is.

You may be asking yourself, "Well, what about flight attendants?" The truth is, many airlines do require flight attendants to wear high heels everywhere but in the aircraft cabin, according to Everyday Aviation.

During flights, most attendants wear flats because of safety concerns and difficulty maintaining balance when hitting turbulence. "You will often see cabin crew in high heels but once the aircraft is underway, they change footwear into a lower rise heel or flats," Manders confirms.

Even if you decide to leave your patent leather peep-toe high heels at home, you might want to avoid other open-toed shoes on a plane as well. Firstly, flight attendant Fischbach says, it's just kind of gross. "Be wary of wearing sandals if you are planning on going in the lavatory," she told Who What Wear. "That isn't water on the floor (yes, use your imagination), and sandals invite whatever that liquid is to splash on your feet." But this shoe choice could be dangerous as well.

Luckily, the chances of experiencing an emergency landing are minimal, but there's another reason why wearing high heels is a risky move, and not just because of the obvious potential to trip or fall. Andrea Fischbach, an American Airlines flight attendant, told Who What Wear that when it comes to footwear, she "would really advise against high heels … mostly for safety purposes."

High heels are notoriously uncomfortable, but that's the least of the problems when it comes to boarding a plane in this fancy footwear. The shoes also pose a potential safety hazard in the case of an emergency situation. "Experts are against the wearing of heels on planes due to how much they compromise the safety of passengers," explains Michelle Halpern, a travel expert and founding editor of Live Like it's the Weekend. She notes that heels could puncture the inflatable slides used for emergency evacuations. "High heels are practically death traps in emergency situations since they reduce reaction time and compromise safety equipment such as slides for emergency landings," Halpern says.

Before 2001, you probably didn't think much about what footwear to fly in, as long as it was comfortable. But ever since we've had to remove our shoes to get through security, that wardrobe decision has become a lot more loaded—you need shoes that don't have complicated ties or buckles, and that are easy to slip on and off so you don't hold up the line. But according to experts, there is actually one type of shoe that some people prefer that you should never wear on a plane, as they could pose more than one major risk. Read on to find out which pair of shoes you should store in your luggage instead, according to flight attendants, pilots, and other experts in the industry.

This should probably go without saying, but violence and terrorism are also absolute no-no's to joke about on planes. "Sometimes the booze is flowing and you're a little bit looser with your lips than you want to be, but jokes about violence, bombs, hijacking, things you have that could be used as a weapon—they're never funny," Orlando says.

Though predictions range, experts say that can be as hot as 50,000 degrees Fahrenheit. If that's hard to imagine, allow us to put it in context: That's three times hotter than the surface of the sun. No wonder any water in lightning's path is immediately vaporized.
