Beware of Vietjet air . whatever they tell you they WILL require proof of onward ticket or they wont let you check in. -@Klmeermpt666Having just entered Vietnam on the 28 Feb. 2024 with VietJet Air I had absolutely no challenges requiring proof of an onward flight. I handed the check in my passport along with a 90-day visa which is standard procedure when entering any country. No visa - no entry. -@Safepeter
I was going to post similar Peter, but being a goodolboy decided just to ignore it. I have used Vietjet from Singapore to Tan Son Nhat & from Chaing Mai to Tan Son Nhat & never been asked or required to have proof of onward travel. Just shows what I have always said.............be careful about posts on a forum & especially statements in bold print, they are not always accurate!!!!! or in everyone's experience.
