Business Class flights to Bangkok take around 11 hours 30 minutes from London. British Airways flies direct from Gatwick, while Thai Airways operates from Heathrow. Both offer the lie-flat seats that make overnight flights to Southeast Asia manageable.
Thai Airways' Royal Silk Class remains a benchmark for the route, with consistently good food and genuine Thai hospitality. British Airways brings its Club World product with the new Club Suite on some aircraft. Gulf carriers like Emirates and Qatar Airways offer alternatives with connections through Dubai and Doha.
Bangkok works as a destination in itself or a gateway to Thai islands and beyond. Business Class gets you there rested and ready, whether you're heading to meetings in the city, beaches in the south, or temples in the north.

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.
