Route guide
London to Bangkok flights — what you need to know
London to Bangkok is Britain's favourite long-haul leisure route east — the gateway to Thailand's islands, honeymoon resorts and the wider South-East Asia backpacking circuit. Thai Airways and EVA Air fly it non-stop from Heathrow in around 11 hours 30 minutes, while one-stops via Doha, Dubai or Istanbul routinely undercut them by £100–£200 for barely two hours more travel.
Thailand's cool season (November to March) is peak everything: best weather, biggest crowds, highest fares. The savvy play is late April to June — hot but dry-ish, hotels 40% cheaper, and flight fares at their friendliest. Bangkok's Suvarnabhumi airport connects seamlessly to Phuket, Koh Samui and Krabi; we ticket the domestic hop with your international fare so your bags check through and a delay never strands you.
8–12 weeks ahead; Christmas and February need 4+ months.
Late April to June, and September to mid-October.
Add Phuket, Samui or Krabi on one ticket — bags check through from London.
