On a recent VietJetAir flight, there was a featured bonus that consisted of an in-flight service that passengers on this discount airline company did not expect. Clad in vaporous string bikini tops and sarongs that flaunted the company colors of red and yellow, young, beautiful women filed down the plane's aisles last Friday for a bikini show.

The plane was on its way from Ho Chi Minh City to the coastal tourist city of Nha Trang. As passengers pulled out their smart phones and video cameras in order to archive their unique airline experience, the young women sashayed up and down the plane, batting their eyelashes at the passengers and handing out toys to children, while the plane was at cruising altitude.

Once the plane was safe and sound on solid ground, the short clips of the beauty show, called a Hawaiian dance performance by the airline, were circulated among popular social networks such as YouTube and Facebook.

Consequently, the budget airline was slapped with an approximately $1,000 fine by the Civil Aviation Administration of Vietnam (CAAV), as reported by the Vietnamese news website, Vietnamnet.

The chief inspector of CAAV, Nguyen Trong Thang, said the fine was administered not because the airline conducted a beauty show but because it had held an "unapproved show" on the plane. Otherwise, because the plane had reached its safe altitude and the passengers who were recording the show had their phones in movie mode, Vietnamnet reports, Thang did not believe that the 3-minute show violated any local aviation regulations.

The roughly 60-minute flight was too short for a good movie or a meal but maybe such a live show could keep customers coming back.

A VietJetAir official told the Daily Mail that the dancing girls in bikinis was a way to "make passengers happy and to improve our customer service."
