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 Istanbul
Istanbul Airport (the new mega-hub, opened 2018) sits 35 km northwest of the city. The new metro extension reaches Gayrettepe in 26 minutes for ₺27. Turkish Airlines is the dominant carrier with Pegasus operating from Sabiha Gökçen (SAW) on the Asian side. Istanbul is the cheapest gateway to Asia from the UK on connecting fares; book well ahead for Hagia Sophia / Topkapı tourism peaks.
