How to get from Seoul airport to city centre by train
Seoul Incheon International Airport and Gimpo Airport are connected to Seoul by train. However, Incheon has an express railway service between Incheon Airport and Seoul Station.
When I arrived in Seoul, I decided to take the express train (called AREX), because it’s a faster way to get to Seoul Station in the city center.
Incheon is far from the city, more than 50 kilometers away. The express train takes 40 minutes, the ticket cost 9,000 Wons (US$ 8.50). And the travel time by regular train is 90 minutes and the ticket cost 5,000 Wons (US$ 4). Tickets can be purchased at counters or at vending machines, it’s very simple to buy.
Express Trains depart every 20 to 40 minutes and the regular train leave the airport every 5 to 10 minutes towards Seoul Station.
After buying the ticket, look for the platforms. On one side are the gates for the express train (AREX) and on the other side the gates for the regular train. You have to insert the ticket do get in and get out of the stations, don’t lose your ticket.
Both services had Seoul Station as final destination. In the Seoul Station you can connected to the Seoul subway network. In both services you can buy the ticket until your final destination, including the connection at Seoul Station and the other lines.
