Airlines like Air New Zelanad and RyanAir have come under fire for their less-than-family friendly promotions, but the Vietnamese low-cost carrier, VietJetAir, is facing backlash over racy publicity photos that weren't part of an official ad campaign. Ngoc Trinh, a Vietnamese lingerie model, recently posted pictures of herself along with other women wearing skimpy bikinis in the VietJetAir’s colors to her Facebook page, according to the Daily Mail. They were allegedly captioned: “Just finished shooting promo photos for VietJet Air for 12 hours nonstop from 9:00 am to 9:00 pm.”
