Incheon International Airport (ICN) serves as Seoul’s primary international gateway and a major regional hub, handling most long-haul and premium carriers along with many full-service Asian airlines. It’s located about 48 km west of central Seoul, with travel times typically around 45–70 minutes by airport express train (AREX) or 60–90 minutes by airport limousine bus depending on traffic; fares for rail and buses usually sit within a moderate range. Taxis can be faster but costlier. ICN is known for modern facilities, extensive lounges, and shopping, though its distance from downtown can add transfer time.
Gimpo International Airport (GMP) acts as Seoul’s nearer, more domestic- and short-haul-focused airport, commonly serving budget carriers, domestic flights and select regional routes to Japan and China. It’s roughly 15–20 km from central Seoul, typically 20–40 minutes away by subway or 30–60 minutes by bus; fares are usually low to moderate. Gimpo can be more convenient for quick city access and shorter transfers, but it offers fewer long-haul services and amenities than Incheon.
