And since I am complaining about travel nonsense... I paid 24usd to have a CHECK bag. Weight limit 15kg apparently. I am 5 kilo over... The fee is 1700 baht. Vietjet is like a Bangkok taxi driver who refuses to use the meter.
Edit: check bag and 15kg limit. I don't know how I made BOTH of those errors. I am going to blame vietjet.
