A flight expert has explained why wearing leggings on a plane may not be the best choice.

Choosing the right outfit for a long flight can be challenging—you want to be comfortable, regulate your temperature, and perhaps even maintain a stylish look.

However, according to aviation experts, certain clothing choices should be avoided when flying.

There have been various recommendations about what passengers should and shouldn’t wear on a plane.

For instance, flight attendants have warned against wearing Crocs or flip-flops, particularly when using the restroom.

“Be cautious if you plan to wear sandals in the lavatory,” one flight attendant advised.

“That isn’t just water on the floor—use your imagination. Sandals leave your feet exposed to whatever that liquid might be.”

Similarly, another airline steward has advised against wearing shorts during flights.

In a viral TikTok video, he explained: “Try not to wear shorts when flying.

“It’s similar to the windows—you never know how clean they are. Wearing pants reduces your exposure to germs.”

Now, an aviation expert is cautioning travelers against wearing leggings on planes.

Christine Negroni, a bestselling author and aviation specialist, has outlined why leggings should be avoided, along with other important travel attire tips.

Speaking with IGV, Negroni recommends wearing “comfortable flats with sturdy soles that are easy to remove.”

“In an emergency evacuation, the ground outside could be cold, wet, icy, extremely hot, or littered with metal, fuel, or airplane debris,” she explained.

“If you use the emergency evacuation slide, high heels must be removed as they could puncture it, making flats the safest choice.

“And while it’s not an official FAA regulation, it’s simply smart to keep your shoes on during takeoff and landing.”

Additionally, Negroni emphasizes that leggings are particularly risky, as they could lead to serious injuries in case of an accident.

She explained: “Most air accidents are survivable, but many involve fire.

“Leggings are made from synthetic materials, which can melt when exposed to heat, potentially fusing to the skin and causing severe burns.

“In 1999, the Federal Aviation Administration recommended wearing garments made of cotton, wool, leather, or even denim instead of synthetics.”
