Belfast is served mainly by two airports with distinct roles: Belfast International (BEF), a hub for a mix of low-cost and charter carriers handling many international and seasonal routes, and George Best Belfast City (BHD), a closer, smaller airport that typically caters to short-haul and business-focused flights. International is about 20–25 miles northwest of the city centre (roughly 30–50 minutes by car) and can be reached by coach services or taxis; fares for shared coaches usually fall in a modest range. City airport sits around 3 miles from central Belfast (10–20 minutes by taxi or regular bus), making it the more convenient option for quick connections. Pros: International offers more route variety and budget options; City offers speed and proximity. Cons: International can be further and sometimes pricier to reach, while City can be busier and has fewer long-haul choices.

London is served by several airports with different roles. Heathrow (LHR) is typically the city’s primary international hub, favored by full-service carriers and many transatlantic and long-haul flights; it sits about 24 km west of central London and is usually reached in 15–50 minutes by the Heathrow Express, London Underground (Piccadilly line) or taxi — fares and times vary by service and traffic. Gatwick (LGW) to the south is often positioned as a large international and leisure gateway with a mix of full-service and low-cost airlines, around 45 km away and commonly reached in 30–60 minutes by Gatwick Express or rail. Stansted (STN) and Luton (LTN) are typically low-cost and charter-focused airports further out, often used by budget carriers; they can be 40–70 km from central London and reached by dedicated express trains or coach services in roughly 30–90 minutes. London City (LCY) is usually the most central and business-oriented, close to Canary Wharf and the financial district, often reached within 15–30 minutes by DLR or taxi but serving fewer long-haul routes. Pros include wide choice and frequent connections across price points; cons can be longer transfers from outer airports, variable fares, and different terminals requiring time to connect.

The cost of a one-way flight from Belfast to London ranges from $22 (July 2026) to $30 (November 2026). On average, the ticket price is about $26–$54.
