I have flown to BKK 15 times over the last 7 years some one way mostly round trip I have never had any issues with airline or immigration. This last trip I arrived on July 13th (yep stupid on my part two days and I would have gotten the 60 day) my departure is Dec 13. They only gave me 30 days 2 days before I went to immigration and receive 30 more days. Went to taiwan came back received 60 days went to immigration got the other 30 days current visa expires on the 13th dec leaving same day.
