Is it OK to fly into Thailand with an antigen (or PCR) test obtained from country A, checking in for the flight from country B (after a 24 hour stopover), provided the results are within 72 hours of the flight departure to Bangkok? I assume yes, but wanted confirmation.
Just as an example here, say I were to fly from Australia to Vietnam with a test result issued in Australia, then spend one night in Vietnam and then fly onto Thailand?
