Seoul is served primarily by two airports with distinct roles. Incheon International (ICN) functions as the main international hub, handling most long-haul and premium carriers and typically offering a broader range of lounges and amenities; it sits about 48 km west of central Seoul with a typical transfer time of 45–70 minutes by AREX express or airport bus, fares generally ranging from modest to mid-level depending on service. Gimpo (GMP) is closer—roughly 15 km from downtown—and usually caters to domestic flights and short-haul routes with low-cost and legacy carriers alike; transfers by subway or airport bus can take 20–40 minutes at economical fares. Pros: Incheon excels for international connectivity and facilities, while Gimpo is more convenient for quick city access. Cons: Incheon’s distance can add transfer time and cost, and Gimpo can be crowded during peak domestic travel.

London is served by a network of airports with distinct roles. Heathrow is the primary international hub, typically handling intercontinental and full-service carriers; it sits about 24 km west of central London and can be reached by the fast Heathrow Express in 15–20 minutes (higher fares), the Piccadilly Line tube in roughly 45–60 minutes (cheaper), or by taxi in 40–60 minutes depending on traffic. Gatwick, south of the city, often mixes leisure and scheduled carriers and is roughly 45 km away; the Gatwick Express takes about 30 minutes to Victoria, while trains and coaches provide cheaper but slower options. Stansted and Luton are generally positioned as budget- and charter-focused airports serving low-cost airlines; Stansted is around 60 km northeast with a 45–60 minute Stansted Express or longer coach rides, while Luton lies northwest about 50 km away and usually requires a shuttle plus train or coach for 30–60 minutes travel. City Airport caters to business travelers and short-haul routes from the east, only about 11 km from the centre and typically accessible by the Docklands Light Railway in roughly 20–30 minutes. Pros: wide choice of carriers and frequencies; cons: longer transfers, variable costs, and potential congestion—especially during peak hours.
