You buy a thai covid insurance. It's quite easy. I buy the one recommended on the thai immigration website. But there are many options. No uk insurance will cover you now.
talking about the whole package starting with flights etc I'm already in Thailand and everything went smoothly. So just my way of doing things. I just wanted the questioner to know there may be many hurdles to jump. So best be prepared.
so easy for you with your experience but not as easy for others from different destinations. For example from uk I received COE within 2 hours but a friend of mine in the USA waited 15 days.
noted! But if you need a visa and the necessary documents. Book asq hotel or sandbox. Book flights. Apply COE. All need careful consideration. Bearing in mind that Thailand will join the red list as of August 30th
