Meet Nguyen Thi Phuong Thao, Vietnam's first female self-made billionaire. Much of her net worth comes from her company VietJet Air, which on its website calls itself a "dynamic, innovative airline." But some might have other words for what it is her company is doing.

Indeed, VietJet isn't known so much for its CEO as it is its bikinied flight attendants. It's a uniform Thao insists is empowering for women in such a conservative country.

"As a businesswoman, I have a responsibility to contribute to the economy and to push for positive changes of the country and in the society, in light of the international integration that's happening," Thao told B.

"You have the right to wear anything you like, either the bikini or the traditional ao dai," she added, with the ao dai being a long tunic traditionally worn in Vietnam.

The airline also profits off of its calendars, which star models in VietJet Air bikinis hanging out on a plane and a tarmac.

Social media slammed the airline when images from a "trial photo shoot" were leaked by one of its starring models and went viral, according to the Telegraph.





I've never scolded an airline until today. @VietjetairCom, you should be ashamed of yourself marketing Iingerie models as fight attendants.

Fellow budget airline Ryanair went through a similar controversy with its own calendars, which used to feature its flight attendants in bikinis, according to the Irish Times. The airline canceled the calendar, which began in 2008, in 2014 after it was called "discriminatory."

In 2012, VietJet Air hosted a "beauty show," in which women danced down the aisle while the plane was at cruising , according to ABC News. The Civil Aviation Administration of Vietnam fined the airline $1,000 for holding an "unapproved show."

VietJet Air currently has 47 destinations in Vietnam and around Asia, It also has of Vietnam's flying market share, Bloomberg reported, and it could very well become the nation's biggest airline.
