Intl-Intl transit at BKK
I hope this is the right forum - if not, let me know.
I have a single booking HKT-BKK-Europe with HKT-BKK on Thai Airways, and BKK-Europe on another *A carrier.
On a booking like that, where will I go through exit immigration and customs, at HKT or BKK? If at HKT - what's the process at BKK?
