Air France has London Heathrow to Bangkok returns from £576, the lowest fare on its own calendar when we checked on 2 October 2026. For a long-haul Thailand trip with a full-service airline, that’s a sharp price.
The £576 fare sits on one specific date pair: out on 7 October, back on 5 November. Other October dates mostly ran from about £770 to £1,140. Air France’s month view showed November from £706 and December from £699, and KLM’s London to Thailand page listed fares from £675.
This isn’t a nonstop fare. You change in Paris with Air France or Amsterdam with KLM, so check the connection times before you book. On a trip this long, a clumsy layover can add hours.
Best fit: travellers who can leave on 7 October and stay four weeks, or anyone planning a November or December trip who wants a fare under £710.
