I just booked my ticket from Frankfurt to Bangkok via thai airways. When booking the website gave me an alert that i might get rejected entry upon arrival if not carrying a return ticket. I study at a university in Thailand and hold a student visa, currently on the second extension of stay. Should I be alright? Also I don't know anything about the current entry regulations regarding covid. I'm vaccinated twice and got the booster shot, do I need anything else? Thanks y'all and have a nice day 😊
