Jaap H F van der Linden They are classed as normal commercial flights, HOWEVER you need to follow the RTE guidance / instructions to apply for a CoE prior to flying into Thailand. You cannot just book and fly.
David Broadfoot yes I could have, but at the end of that 60 day I’d still have to leave. Getting back in as I’m sure you are aware isn’t straightforward. For me a 12 month extension and not having to leave made more sense.
