Flying from London Heathrow
Heathrow is the UK's main long-haul hub and the airport where full-service carriers concentrate their schedule rather than chase price. Expect five terminals, fast Tube and Elizabeth Line links into central London, and a route map that skews toward business-traveller frequency: more daily slots, fewer fare wars. Short-haul fares from Heathrow tend to run a little higher than Gatwick or Stansted on the same corridor — the trade-off is a wider choice of airline and a more reliable timetable.
Arriving in Bangkok
Bangkok Suvarnabhumi sits 30 km east of the city, with the Airport Rail Link (ARL) reaching Phaya Thai in 26 minutes for ฿45. Thai Airways, BA, Eva Air and Qatar (one-stop) all operate the route. Bangkok is the most reliably cheap long-haul UK route — high season (November–February) sees price spikes, with April–October typically delivering the best fares despite the rainy season.
