The only reason uk would put Thailand back on the list in December is if Thailand had a massive amount of Covid-19. Its not that difficult to understand π€£π€£
I'm in a similar situation..if you fancy a trip to Turkey then it's all open and I believe get 90 day visa on arrival for Thais and us citizen.. think it's the only option at the moment π
Two weeks self isolation pal. They will make you fill in a form on arrival to say what address you will be in. Β£1000 fine if caught leaving that address
Possibly a couple of countries missing off the list. But also many more countries like India where an e visa is simpleto get. In normal circumstances . ππ
