Incheon Airport to Gangnam & COEX 2026: 6703 Bus, AREX/Subway or Taxi
Best choice with luggage: K Airport Limousine 6703 is the most convenient direct public-transport option for many Gangnam and COEX hotels. If your hotel is not near a 6703 stop, AREX plus subway can be cheaper and more predictable. Taxi is easiest for groups and late arrivals.

AREX + subway
A rail route requires at least one transfer, but avoids road traffic. Your best transfer depends on the exact Gangnam destination. Use NAVER Map to plan the final subway route after you know your hotel address.
For COEX, you will usually aim for Samseong Station (Line 2) or Bongeunsa Station (Line 9).
Taxi
Gangnam is farther from Incheon Airport than central Seoul, so a taxi is significantly more expensive than the limousine bus. Standard taxis use meters; expressway tolls and night surcharges can apply. It can still make sense for a family or group splitting the fare.
Late-night option
K Airport Limousine currently operates N6703 night service toward Gangnam. The official route includes Samseong and other southeast-Seoul stops, but the late-night stop pattern is not identical to the daytime 6703. Check the current N6703 page before boarding.
How foreigners can pay
For the airport limousine, use the airport ticketing channel or operator ticketing option shown for your terminal. International-card acceptance can depend on the payment terminal and issuer. If a kiosk rejects your card, use a staffed counter or another supported payment method.
