Did it not say where you went wrong. Seemingly any new applications supersede previous. So I do not see any point in applying more than once. Saying that, some have had several accepted.
Andy, It’s Thai law which is more important than the airline. Airlines now know this. As long as it says PCR people will be fine as was proved last week when I entered 😎
I’m reading some comments saying 72 hours from result. So in that case, I could request the laboratory not to issue my results until as late as possible? Maybe even a week after test? It does not make sense unless it’s time from swab test.
