Incheon International ICN
Cheap flights from Incheon International are what most long-haul trips to South Korea begin with. ICN is the big international gateway for Seoul, while Gimpo International handles the shorter, mostly regional traffic, so it pays to check both before you commit. From Incheon you can look for fares to Warsaw, Budapest, Frankfurt, Istanbul, Chisinau, Prague, London and Paris, and the price calendar shows how much they shift from month to month.

Getting to the city
Getting into Seoul from Incheon takes planning. The airport rail link and express coaches run to the city centre, and taxis are the fallback when you land late. Allow time for immigration and baggage before you count on a tight onward connection, and if your flight arrives after the last train, arrange a cab or a night bus seat before you fly. If your hotel sits on the far side of the city, compare the rail link with a coach, because expressway traffic can stretch a short hop into a long one.
