Nonstop from London Heathrow
British Airways, EVA Air and Thai Airways. Heathrow is the only airport in the United Kingdom with a nonstop to Thailand, and Bangkok is the only Thai airport it serves. Everything beyond Bangkok is a domestic connection.

The quickest connections are the short European ones, through Copenhagen, Amsterdam, Munich or Zurich, at about 13 to 14 hours all in. The Gulf carriers through Abu Dhabi, Doha and Dubai run nearer 15, and Singapore nearer 16. A long layover can add three hours to any of them.
