Do I need a transit visa at Don M. Airport in Thailand during my trip to Tokyo from Dhaka, Bangladesh?
Because, I will travel on two separate airlines; Dhaka-Bangkok of Thai Lion Airways and Bangkok-Tokyo of Air Asia.
I will return in the same way.
There are 6:30 hours of stopover on the road to Tokyo and 3:30 hours of layover on the road from Dhaka. I have no check in luggage.
If a visa is not required, then: How can I manage the Air Asia boarding pass in Bangkok without crossing immigration?
