5240 km great-circle distance, typically flown in 6h 57m with 10 airlines operating direct service from London Heathrow (LHR) to Boston Logan (BOS). 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 Boston
Boston Logan sits 5 km northeast of downtown Boston, with the Silver Line bus running directly to South Station in 15 minutes (free for arriving passengers). BA, Virgin Atlantic and JetBlue serve the route. Boston is the closest US East Coast city to the UK by flight time and often the cheapest US route from London — autumn foliage season (October) is the price peak.
