Updated 2026-07-20
10881 km great-circle distance, typically flown in 14h 00m with 10 airlines operating direct service from London Heathrow (LHR) to Singapore Changi (SIN). Fares on this corridor stay relatively stable across the year — booking 4–8 weeks ahead and choosing a midweek departure typically secures the best price.
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 Singapore
Singapore Changi is consistently rated the world's best airport — 18 km east of the city, with MRT trains reaching downtown in 30 minutes for S$1.80. Singapore Airlines is the dominant carrier; BA and Qantas add full-service slots. The route is the longest non-stop from the UK at around 12.5–13 hours; off-peak fares are surprisingly competitive given the distance — book 8–14 weeks ahead.
