Incheon International Airport ICNRKSI

Incheon International Airport (ICN) is Seoul’s main international airport and a major Northeast Asia connecting hub, while Gimpo is more useful for domestic and nearby regional flights. Korean Air anchors the SkyTeam presence at Terminal 2; Asiana has moved to Terminal 2 as part of its integration with Korean Air, while Star Alliance benefits for Asiana remain in transition until its announced Star Alliance exit in December 2026. Terminal 1 still handles many foreign airlines and low-cost carriers. For most city-bound frequent flyers, AREX to Seoul Station is the simplest baseline: about 43 minutes from T1 or 51 minutes from T2 on the nonstop train, with all-stop trains taking roughly 59 and 66 minutes. Transit is generally efficient, but terminal changes matter: follow green Transfer signs and use the airside shuttle train for T1/Concourse/T2 movements; verify your terminal on the ticket or airport flight search, especially on codeshares.
