Can find nothing on the TG website for domestic travel and no point calling so maybe someone can confirm if we need a covid test to fly Suvarnabhumi-Hat Yai?

Passengers are vaccinated. Thanks

I flew Thai Smile in Feb from BKK to CNX.  I showed my vaccination card to prove I had two doses of Pfizer.  This was good enough to get my boarding pass.  Each airline might have a slightly different policy but I would believe the key factor is whether or not your are fully vaccinated or not?  If you are not vaccinated then either you can’t fly or have to show a negative Covid test.  

No test required if vaccinated.

Even the vaxx cert. are checked loosely.

 

The age old formal rules seem still unchanged:

But as written some airlines take it very easy.

Thank you for the replies. My wife just got through to TG on the phone with a five minute wait which surprised me. I thought she would be on the phone for an hour or more. TG confirm no test required.
