The answer to that question is no. There have been no scheduled international flights to U-Tapao, Krabi, Chiang Mai, Chiang Rai, or any other of the smaller Thai airports formerly catering to international arrivals since spring last year.
Maybe a few international charters, but these, if any have been in extremely small numbers,
The Thai airline industry is in very bad shape, kept alive by mainly internal flights.
TG is a basket case, but has been for years, anyway.
