I'm also cancelling return flight I booked when in Thailand, only have return flights booked to get on board plane. Once in Thailand will change dates of return flight
I arrived December 1 night quarantine only thing had booked. Got asked at immigration just told them hotel name I knew they accepted that . I had 60 day visa
I think insurance still should be mandatory but each to their own. Non O is less hassle I think, getting doctor sign off medical certificate here is a struggle, my doctor basically doesn't want sign anything....they have no idea what its about. Like most things in uk now nobody knows what they are doing.
