When you think of VietJet Air, bikini-clad models and stewardesses come to mind.
This festive season, the airlines has released, yet again, their 2018 calendar featuring models dressed in lingerie with the company colours - red and yellow.
This year's theme "air cabin catwalk" sees models posed as different cabin crew and staff.
Among them include Celine Franch, a 20-year-old American model who has over 950,000 followers on Instagram.
The calendar also features Thai runner-up of Miss Tiffany's Universe 2017 Kwanlada Rungrojampa (Rock Kwanlada).
Vietnamese runner-up of the Asia’s Next Top Model 2017, Ming Tu Nguyen, was also involved in the photo shoot.
A VietJet Air spokesperson told Taiwan News that they worked hard to recruit top models from different countries.
VietJet Air is known for using scantily-clad girls in its promotional campaigns.
In 2014, the airlines was slammed for featuring bikini girls in its cabin in an apparent PR promotional stunt.
Although cabin crew on VietJet Air are fully-clothed, the airline does occasionally offer special flights with the official bikini uniforms.
According to VietJet Air CEO Thi Phuong Thao, the calendars and bikini crew are "empowering images in Vietnam's conservative culture".
She told Bloomberg: “You have the right to wear anything you like, either the bikini or the traditional ao dai (traditional Vietnamese longtunic worn over loose pants)."
