I'm taking an internal flight, but my passport is with the Labor Dept. Can I use my Thai driving license as valid ID? Or I have dual nationality, can I use my other passport?
TLDR : Answer Summary
Users confirm that you can use either a Thai driving license or your other passport for domestic flights within Thailand, especially if your main passport is with the Labor Department. Some users note past experiences indicating that airlines might have different requirements, but recent updates suggest both forms of ID are acceptable.
