I apologize if this is not allowed. I have a US passport. I have been living in Thailand for over a year. I have a flight from Chiang Rai to Bangkok, and then Bangkok to Seoul.Then I have a flight from Seoul to the US. Can anyone tell me if Thailand will require me to show a fit to fly certificate?
TLDR : Answer Summary
A fit to fly certificate is not required for leaving Thailand on international flights, including the user's journey from Chiang Rai to Seoul. However, travelers should be aware of the health requirements of their transit country (South Korea) and ensure they are compliant, especially as they may need to complete health questionnaires or undergo temperature checks.
