Video of the five girls, all former beauty queens, dancing in bikinis in the center of the plane went viral on YouTube, where it has more than 254,000 views. (You can watch the bikini strutting below.)
VietJet Air offered the unconventional in-flight entertainment during an Aug. 3 flight from Ho Chi Minh City to Nha Trang, according to the Associated Press. The flight was the first to Nha Trang operated by the budget airline.
Because Vietjet did not have approval to have the girls strut in bikinis mid-flight, the Vietnamese government fined the airline 20 million dong ($960.)
Nguyen Trong Thang, chief inspector of the Civil Aviation Administration, said the fine was levied because Vietjet "violated local aviation regulations" because the girls in bikinis constituted "an unapproved show on a flight," according to AFP.
In the viral video, girls in red bikinis can be seen moving their hips and dancing in the aisle of the plane as giddy male passengers snapped away on their cell phones. The beauty queens gyrated to a song that included the lyrics, "I go crazy for banana."
After the dance, the girls gave out white teddy bears to passengers on board the inaugural flight.
A VietJet executive told the Daily Mail that the performance did not affect the safety of the flight. Nha Trang is on the southern coast of Vietnam, which led the airline to dress up the girls in a beach theme.
"It was the first flight to a beach town, so we came up with the idea of getting a number of girls in bikinis to dance and make passengers happy to improve our customer service," the exec told the Daily Mail.
A VietJet representative said the beauty queens were paid for their performance and acknowledged the company was fined, but did not go into further detail about the incident, AP reported.
VietJet is a privately owned company and took off on its inaugural flight in December, according to AP.
