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?
TLDR : Answer Summary
The inquiry discusses the validity of a COVID test for entering Thailand after a stopover in Vietnam. It confirms that a lab-issued antigen or PCR test result from Australia can be used, provided it is done within 72 hours of departure to Bangkok. Additionally, it highlights the importance of confirming with the airline regarding their specific acceptance of the test results due to potential varying policies.
