Seoul is served primarily by two airports with distinct roles. Incheon International (ICN) is the region’s main international gateway and a long-haul hub for full-service carriers; it typically handles most intercontinental flights and can be pricier to reach but often competitive for transpacific routes. The airport lies about 48 km west of central Seoul, with express train options (Incheon Airport Railroad Express) taking roughly 45–60 minutes and airport buses around 50–70 minutes; fares typically range from moderate to higher depending on service. Gimpo Airport (GMP) acts more as a domestic and short-haul regional node, frequented by low-cost and legacy carriers for flights to destinations across Korea, Japan, and China. Located roughly 15–20 km from downtown, Gimpo is reachable by subway in about 20–30 minutes or by taxi in similar time with lower fares. Incheon offers extensive amenities and international transfer convenience but can mean longer surface travel; Gimpo is often more convenient for quick domestic hops though with fewer long-haul services.
