Incheon International Airport ICNRKSI

Incheon International Airport (ICN) is Seoul’s main international gateway and one of Northeast Asia’s most important long-haul transfer airports. It is the core international hub for Korean Air and a major SkyTeam operation, with Korean Air, Delta, Air France, KLM, Asiana and several other SkyTeam or Korean Air group carriers using Terminal 2. Terminal 1 handles a broad mix of foreign full-service airlines, low-cost carriers, Star Alliance and oneworld operators, plus the T1 Concourse reached by an airside train. For Seoul, the AREX rail link to Seoul Station is usually the cleanest city-centre option, roughly 45–60 minutes depending on terminal and train type. ICN is very transfer-oriented: airside hotels, nap/relax zones, showers, transit tours and a strong lounge ecosystem make it comfortable for long layovers, but self-transfers and terminal changes should not be planned too tightly.
