Passengers flying Spirit Airlines may need to conceal some tattoos or put on more clothing for their next flight, according to the airline’s updated contract for travelers.

Passengers may not be allowed to board Spirit Airlines flights if their tattoos or clothes are deemed “offensive,” according to an updated contract between travelers and carriers. Airline officials updated Spirit’s contract of carriage on Wednesday,

Spirit Airlines has updated its contract of carriage to specify what types of clothing and body art are allowed on board.

According to Spirit, guests who don't adhere to the clothing policy could be denied boarding or asked to leave the aircraft.

Inappropriate behavior is usually one of the top reasons you see people removed from commercial airline flights, but if you’re flying on Spirit Airlines, your choice of clothing and your body art could result in you being left at the gate.

Spirit Airlines customers have to don unprovocative clothes that do not expose “breasts, buttocks, or other private parts” when aboard the low-cost carrier, according to new standards posted this week.

Some of the updates give examples for already-existing rules, but new restrictions on 'lewd' tattoos and body art are a new addition.

Spirit Airlines is taking a clearer stance on what passengers can and can't wear on its planes, banning visible "private parts" and lewd tattoos.
