London is served by multiple airports with distinct roles. Heathrow is the city’s major international hub, typically handling long-haul and premium carriers alongside many full-service European airlines; it sits about 25 km west of central London and is usually accessible by Heathrow Express (15–20 minutes to Paddington), the Piccadilly Line tube (50–60 minutes), or taxis (30–60 minutes), with fares and journey times varying by route and time of day. Gatwick, an important international and leisure gateway to the south, is around 45 km south of the centre and is commonly reached via Gatwick Express (30 minutes), Thameslink or Southern trains (30–45 minutes) and coaches; it can be perceived as slightly cheaper on average due to more leisure and low-cost services. Stansted and Luton primarily serve budget and charter airlines, positioned roughly 40–70 km to the north-east and north-west respectively; both are usually connected by dedicated express trains and frequent coach services (35–50 minutes from Stansted by train, 25–45 minutes from Luton by shuttle/train), offering lower typical fares but longer total travel times. London City Airport, close in the Docklands area about 11 km east of the centre, tends to cater to business and short-haul flights with quick transport options such as the DLR (10–20 minutes to Canary Wharf) and taxis; it’s often chosen for convenience despite a higher ticket cost perception. Pros across the network include wide airline choice and frequent services; cons can include variable transfer times, congestion during peak periods, and sometimes higher ancillary costs for budget carriers.

Belfast is served primarily by Belfast International (BFS) and George Best Belfast City (BHD). Belfast International, located about 24 km northwest of the city, functions as the larger, mixed international and low-cost hub with many budget and leisure carriers; journeys to the city center typically take 25–40 minutes by car or airport shuttle, with fares for buses or coaches usually moderate. George Best Belfast City sits closer at roughly 3 km from downtown and tends to host regional and short-haul services, including some business-oriented flights; a taxi or bus will usually take 10–15 minutes and costs are generally lower due to the short distance. Pros: quick access from the city via the city airport and a wider route network at the international site. Cons: separate locations can be inconvenient for transfers, and schedules may be limited outside peak seasons.

The cost of a one-way flight from London to Belfast ranges from $23 (October 2025) to $44 (February 2026). On average, the ticket price is about $32–$66.
