What the difference costs (derived arithmetic): to Terminal 1 the express fare is ₩13,000 − ₩4,750 = ₩8,250 more than the all-stop fare, and it saves 59 − 43 = 16 minutes. To Terminal 2 it is ₩13,000 − ₩5,350 = ₩7,650 more and saves 66 − 51 = 15 minutes. These come from the official figures, not from a specific departure: the official page says some all-stop trains take 2–6 minutes longer.

The official page prints a full station-to-station matrix. The Seoul Station column is shown above; for any other pair, open the official page. The matrix's last row (Terminal 2) has no matching column header, so its values read against the stations from Seoul Station to Terminal 1, in order.

Common questions
Is the express train worth the extra fare?
On the official figures it is faster by 15–16 minutes and gives you a reserved seat. The all-stop train is the cheaper choice and the only one that serves the stations between Seoul Station and the airport, such as Hongik Univ. and Gimpo Int'l Airport.
Do the pages show a date?
No. The pages print no revision date; they were read on 2026-10-19. The AREX corporate site also carries fare-notice posters dated 2023-09-01 and 2024-12-13, but they are images and PDF files whose text could not be read, so none of the numbers above come from them.
Not covered here: timetables, partner hotels, City Airport Terminal check-in details, and the list of affiliate cards.
