I will be traveling from Laos with Lao Airlines, transiting in Bangkok to Colombo with SriLankan Airlines, the upcoming end of September. My flight with Lao Airlines will arrive in Bangkok at 19:40, and my SriLankan Airlines flight leaves Bangkok at 21:50. I will be 2:10 hours in transit.
Will this be enough time for the transit?
Do I still have to pass Immigration & Customs at Bangkok to check in my bags for my other flight, given that it's two different airlines?
I have a European passport.
