Well i made it.
Day 1: Tested early morning EU time, got the result late afternoon and submitted all the info for Thailand pass
Day 2: woke up was approved for Thailand pass
Day 3: Flight at 5pm EU time
At check in had to show TP, PCR test and insurance. In Bkk showed only Thailand pass. A380 from Doha was full both eco and biz.
Arrived here some 15 hours later and no issues with the Thailand pass. There were issues because of my previous 2 years of covid extensions and trying to enter Visa exempt, even got sent pack to the desk but at the end was let in. Told to get a Non-o next time to avoid problems.
