First Class flights to Bangkok from the UK are available via connecting services, as direct flights from London operate in Business Class. Thai Airways offers First Class on some of its Heathrow services using Boeing 777 or Airbus A350 aircraft. For guaranteed First Class, Emirates via Dubai, Qatar Airways via Doha, and Singapore Airlines via Singapore are excellent options.
British Airways resumed London Gatwick to Bangkok services in late 2024 but uses three-cabin aircraft without First Class. The best First Class options are through Thai Airways when available, or via Middle Eastern and Asian hubs where First Class is consistently offered on long-haul segments.

Many of the flights and flight-inclusive holidays on this website are financially protected by the ATOL scheme. But ATOL protection does not apply to all holiday and travel services listed on this website. Please ask us to confirm what protection may apply to your booking. If you do not receive an ATOL Certificate then the booking will not be ATOL protected. If you do receive an ATOL Certificate but all the parts of your trip are not listed on it, those parts will not be ATOL protected. If you have booked a flight only where the ticket is not issued immediately, your flight will be protected under our ATOL. Please see our booking conditions for information, or for more information about financial protection and the ATOL Certificate go to ATOL Certificate
