Seoul is served by two main airports with different roles. Incheon International (ICN) is the city’s primary long‑haul gateway and a major international hub, typically handling most intercontinental and full‑service carriers; flights here can be comparatively higher in price but offer broad route choices. It sits about 48 km west of central Seoul, with the airport railroad (AREX) taking roughly 45–60 minutes to Seoul Station and express trains slightly faster; bus rides are around 60–90 minutes depending on traffic, and fares usually range from moderate to premium. Pros: modern terminals, plentiful amenities and baggage options; cons: longer transfer time to downtown for some travelers. Gimpo International (GMP) functions more as a domestic and short‑haul regional airport, commonly used by budget and Korean domestic carriers as well as some nearby international flights to Japan and China. Located roughly 15 km from central Seoul, it’s often quicker and cheaper to reach — AREX and metro lines can connect you to the city in about 20–30 minutes, with airport buses and taxis offering similar or slightly faster door‑to‑door times; fares are typically lower than Incheon. Pros: convenience and shorter city access; cons: fewer long‑haul options and more limited international services.
