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.
