Seoul is served by two main airports with distinct roles. Incheon International (ICN) is the city’s long-haul hub and usually handles most international and premium carriers; it’s located about 48 km west of downtown and can take roughly 45–70 minutes by express rail or 60–90 minutes by car depending on traffic, with train fares typically in the mid-range. Gimpo Airport (GMP) functions more as a domestic and regional gateway, often used by low-cost and domestic carriers, and sits around 15 km from the city center—travel times of 20–40 minutes by subway or 30–60 minutes by taxi are common. Pros: Incheon offers extensive facilities and international connections; Gimpo is quicker for domestic hops and closer to central Seoul. Cons: Incheon’s distance can add transit time and cost, while Gimpo has fewer long-haul options.
