Thailand Domestic Turnarounds
I've done domestic turnarounds on domestic TG flights at BKK, DMK, CNX, CEI, HGN, HKT, KBV, URT, HDY, UTH, KKC, UBP, which is all the TG domestic destination (on TG metal) with the exception of USM which I haven't yet tried. DMK is no longer utilized by TG so no longer applicable. There was no issues at any of these airports in doing a turnaround. For each of the airports I've done turnarounds without an onward boarding pass and had plenty of time to exit and go to check-in to get my return boarding pass, then make my way to the lounge to await my flight.
