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 Dublin
Dublin Airport is 10 km north of the city, with Aircoach and Dublin Bus 16 services running direct to the centre. Aer Lingus and Ryanair both have major bases here; BA and easyJet add UK-regional service. Dublin is the cheapest international option from most UK airports — short flight times, no visa for UK passport holders, and budget capacity holds prices down.
