Bit of an odd one, a mates work have taken her passport to do her 90 day report and booked her a flight. She hasn't got the passport back yet but have told her she can take the domestic flight using her work permit. Sounds odd to me but is it true? You can fly with only a work permit?
TLDR : Answer Summary
A user's friend has been told she can take a domestic flight in Thailand using only her work permit since her passport is currently with her employer for a 90-day report. This raises the question of whether it's indeed permissible to fly domestically without a passport, relying solely on a work permit. Generally, while a work permit is primarily a document for employment, in certain situations, it may be accepted for identity verification, but this can vary by airline and specific circumstances.
