Most airlines require shoes at the bare minimum; others have stricter dress codes
United Airlines pilot hugs the passenger who saved his life with bone marrow donation
A United Airlines pilot took a moment to step out of the cockpit and give a hug to the flight passenger who saved his life eight years ago with a bone marrow donation.
Air travel has certainly changed over time, and what once was an occasion that mandated dressing smartly has become considerably more casual.
Recently, Spirit Airlines issued a new dress code for its customers, after several news-making instances regarding customers being removed from flights due to their attire.
Now, customers on Spirit Airlines are subject to be removed from its flights if they are "barefoot or inadequately clothed (i.e., see-through clothing; not adequately covered; exposed breasts, buttocks, or other private parts), or whose clothing or article, including body art, is lewd, obscene, or offensive in nature."
Here are some other rules that airlines have regarding clothing. Do any of these surprise you?
1. Hawaiian Airlines
Passengers on Hawaiian Airlines are prohibited from wearing bathing suits, and "clothing must cover the upper part of the torso," says its Contract of Carriage.

Shorts are fine, but "speedos and bikini bottoms are not allowed," said Hawaiian Airlines. And bare feet are not okay either.
"In all cases, clothing must not be lewd, obscene, or patently offensive to others," said Hawaiian Airlines.

"Depending on your destination, there are different rules and regulations regarding the type of clothing you should wear. The dress code is designed to ensure passengers' comfort and safety while traveling, so it is important to understand the rules before departing," said Qatar Airways.
This dress code prohibits shorts, sportswear, and "overly revealing clothing," and business class passengers should be dressed "smart casual."
"Passengers should pay attention to the dress code when traveling in business class, as it will ensure their comfort and respect for other passengers," said Qatar Airways.
