Budget carrier Spirit Airlines likes to tout itself as “the home of the Bare Fare,” but this probably isn’t what the carrier had in mind.

Customers on a Spirit flight from Las Vegas witnessed an unusual scene this weekend after one passenger on the flight allegedly stripped naked during boarding.

"He removed his clothes and then approached a flight attendant," airport spokesman Chris Jones says to NBC Las Vegas. "Metro officers were called and he was given medical attention."

The incident happened Saturday on a Spirit flight bound for Oakland. The passenger was held for observation by authorities and medical personnel after what local media outlets described as a “medical episode," according to The Associated Press.

Following the incident, Spirit Airlines Flight 359 took off about 30 minutes after its scheduled 11:28 a.m. departure time and landed in Oakland at 1:18 p.m., about 20 minutes late, according to flight-tracking service FlightAware.

Coincidentally, one of Spirit’s marketing taglines touts it as “home of the Bare Fare,” a message meant to play up Spirit’s rock-bottom based fares that are stripped of perks like seat assignments and baggage allowances.

Spirit also ran promotional videos in 2014 that showed two young good-looking actors strip down to their underwear, all part of a “how to” video on how fliers could pack a bag small enough to skirt Spirit’s various bag fees.
