Seoul is served chiefly by two airports with distinct roles. Incheon International (ICN) functions as the premium international hub, handling most long-haul and full-service carriers and often seen as the city’s main gateway; it lies about 48 km west of downtown and can take roughly 45–70 minutes by AREX train or 50–80 minutes by expressway shuttle, with fares typically ranging from moderate to higher depending on service. Gimpo Airport (GMP) operates as a more domestic and regional option, popular with low-cost and short-haul domestic flights as well as some international routes to nearby countries; it’s roughly 15 km from central Seoul and reachable in 20–35 minutes by subway or taxi for a lower fare. Pros: Incheon offers extensive facilities and international connectivity, while Gimpo is quicker for central access and often cheaper for short hops.
