In 2025, I have entered Thailand by air, stayed 60 days via visa exception, went to Laos for one day and re-entered Thailand for an additional 60 days stay. Then I got a 30 days extension and left Thailand in December.
Now I plan to fly through Thailand to Vietnam, and pretty much all flights require a self transfer in Bangkok Airport, where I have to enter Thailand, pick up my baggage, check in for the other flight and exit Thailand again.
I worry that the immigration might not let me in, even though I am just staying one or two hours, as I have stayed 150 days in the last 12 months already.
What is the best way to avoid any issues, should I get a tourist visa for Thailand or pay 2000 thb for the VIP entry services (never tried it, does it work?)?
