Belfast International Airport

Belfast International Airport is the largest airport in Northern Ireland by passenger volume and annual movements, serving the Belfast metropolitan area's roughly 635,000 residents and drawing catchment from across the province and parts of the Republic of Ireland's border counties. Located 13 mi (21 km) northwest of Belfast city center at 268 ft (82 m) elevation near the village of Aldergrove in County Antrim, BFS handles 96 routes across 54 destinations through 7 airlines — a destination count unusually high relative to airline count, reflecting the route network's concentration among a small number of LCC and charter operators serving high-volume UK and Mediterranean leisure markets. EasyJet operates BFS as one of its UK bases and the dominant carrier by departures, with a mix of British and European leisure service. Jet2 runs an equally significant operation focused on Mediterranean and Canary Islands leisure destinations with its signature vertically integrated package-holiday model. Ryanair, TUI Airways, KLM (the sole full-service scheduled operator with Amsterdam service supporting business connectivity), and charter operator Titan Airways round out scheduled service. Destinations concentrate on London-area airports (particularly Luton, Stansted, and Gatwick), Scottish hubs (Edinburgh, Glasgow, Inverness), Manchester, Liverpool, Birmingham, Bristol, plus the full Mediterranean summer ladder — Málaga, Alicante, Palma, Ibiza, Faro, Tenerife, Lanzarote, Gran Canaria — and year-round service to Kraków, Warsaw, Prague, and Amsterdam. The airfield has two asphalt runways — 07/25 at 9,121 ft (2,780 m) as the primary and 17/35 at 6,204 ft (1,891 m) as crosswind — capable of full narrowbody operations and historically significant for transatlantic ferry flights. A single passenger terminal, rebuilt and expanded in stages through the 1990s and 2000s, handles all commercial traffic. BFS shares its airfield with RAF Aldergrove, a Royal Air Force and Army Air Corps installation that operates rotary-wing assets including Islander surveillance aircraft — a dual-use arrangement that traces back to the airport's origins as a World War II RAF training base. George Best Belfast City (BHD), closer to the city center, handles competing domestic traffic but has significantly lower overall volume than BFS.
