Captain, I'm sure you can get low cost flights to London so you should consider via London.
Last time I flew out here from London there were loads of Belgians on the flight heading for Pattaya that had flown in early the same day from Brussels.
There's some cheap deals still for November from London to BKK with QATAR or ETIHAD for under 400 Pounds including taxes and even EVA AIR are only 428.
Here's a few examples with
