I am arriving at Incheon International Airport?

If you have one or two suitcases, the AREX airport train is the fastest and cheapest. The express runs to Seoul Station in 43 minutes for 11,000 won; the regular all-stops train is 4,750 won and only slightly slower.

If you have heavy luggage or a hotel near a specific bus stop, the airport limousine buses are convenient — routes like 6001 (Myeongdong), 6002 (Sinchon), 6015 (Itaewon) cost 16,000-18,000 won and drop you near major hotels. Taxis make sense for late-night arrivals or groups of 3+; Gangnam runs around 70,000-90,000 won, with a small late-night surcharge after midnight. Pre-book a Kakao T Venti for larger groups or families with kids.
