Just come through (2hours ago!) Asked to see it on the phone, everyhing seems a breeze now and everyone quite relaxed, quite different from 3 months ago, even the immigration staff was smiling and pleasant!!!
I flew klm, in february and was checked for vaccine certificate, covid insurance, covid test (n/a now), thaipass at Newcastle, then it was all checked again at Amsterdam (even though i was in transit and same airline) and again all checked in BKK along with visa
Oh, thanks for the info, i land on the 20th May on a one way from uk, i have (luckily) bought a cheapy onwards to vietnam just incase immigration checked so rekon i should be ok.
