Common Thai Airways check-in problems
BKK self-service kiosks limited to Thai citizens
Problem: Some THAI self-service check-in kiosks at BKK only accept Thai national IDs.
Solution: Foreign passport holders should use online check-in via app/web, or use the manned counter at BKK row Q–U.
Codeshare flights need partner check-in
Problem: Star Alliance codeshare flights (United, ANA, etc.) cannot use Thai's online check-in.
Solution: Check the operating carrier on your booking. Use that airline's website (e.g. united.com) for online check-in.
