Seoul is served primarily by two airports with distinct roles. Incheon International (ICN) is the city’s large international hub, handling most long-haul and many transfer flights and typically hosting major full-service carriers and global alliances; it’s located roughly 48 km west of downtown Seoul and can be reached by the AREX express (about 43–53 minutes) or by regular train and airport buses (50–80 minutes), with fares generally ranging from mid-tier to higher depending on service. Gimpo (GMP) acts as a nearer domestic and short-haul gateway that also handles some regional international routes and is usually favored by budget-conscious or time-sensitive travelers; it’s about 15–20 minutes from central Seoul by subway or 20–40 minutes by taxi, with low to moderate fares. Pros of ICN include extensive facilities, transit connections, and shopping, though transfers can add time; Gimpo is more convenient for central access and quicker turnarounds but has fewer long-haul options and sometimes more limited amenities.
