AXA Thailand? I remember reading last year someone bought AXA from a European country and it was not the same. The certificate that AXA Thailand sends you has all the requirements on it that the officials are looking for.
I used them last year to enter Thailand under the asq scheme and their certificate and coverage was approved by Thai authorities . I never had to make a claim so can't comment on if they actually pay out on claims. This time I'm using AXA from Thailand as I know they will cover hospital quarantine if I test positive or happen to be unlucky enough to be seated next to someone who tests positive.
you could buy a second hand bike privately and ride that as long as the registration and taxes are up to date. However, you won't be able to re register in your name.
The day you arrive and check in is not counted regardless of when you check in. I went through it back in December and in total was 15 nights and 16 days.
depends on where you go to do the extensions. When I did my first one (30 days) I asked if I could get the 60 days covid extension and they said no I had to get the the entitled 30 days first. At the time I read on some post that some people were able to get the 60 days covid extension right away. I went to Samui Immigration. FYI the last day to be able to get a 60 days covid extension is May 30th. Unless things change and they extend this date as they did many times before. But if I were you, I would go before the 30th just to be safe. Good luck. As for TM30. I've never been asked for it.
