Airport Railroad (AREX) Express Train

The Airport Railroad (AREX) Express Train is a quick and convenient way to travel between Seoul Station and Incheon International Airport. From Seoul Station, you can continue on to other locations in Seoul by metro or bus, where you can visit sights, restaurants, shop, and join local tours.

The cost of traveling between Seoul Station and Incheon International Airport is 9,500 won for adults and 7,500 for children. The travel time is about 43 minutes nonstop from Terminal 1 and about 51 minutes from Terminal 2, with a brief stop at Terminal 1.

Tickets for the express train can be purchased in person at the express train counter or self-service tickets machines. Both the counter and machines accept both Korean won and credit/debit cards, but the ticket machines often declines non-Korean cards. If so, you can head over to the counter to purchase your tickets using your card. Tickets can also be purchased in advanced through the official AREX website or through third-party websites such as Klook.

The express line train runs nonstop between the 2nd floor basement of Seoul Station and Incheon International Airport (Terminal 1 and Terminal 2). The regular All Stop Train takes 53 minutes and stops at ten major subway stations along the way.

The seats on the express line train are much more comfortable than the seats on the All Stop Train, especially arriving tired after a long international flight.

There is overhead storage for smaller, carry on sized luggage. There is also room for larger sized luggage at the ends of each train car.
