Using AREX Express for the first time is simple, but you should still note a few points below to avoid confusion and make your journey smoother:

Imagining AREX Express will stop midway like AREX All Stop

AREX Express only runs directly between Incheon Airport and Seoul Station, without stopping at intermediate stations. If you want to go to Hongdae, Myeongdong, or other areas, you need to get off at Seoul Station and then transfer to the subway.

Getting off at the wrong All-Stop Train station

At Incheon Airport, there are two separate stations: AREX Express Train and All Stop Train. The two stations are close together but are on different lines. Carefully check the “AREX Express” sign before entering the gate.

Buying tickets close to peak hours

Early morning and late evening trains often fill up quickly, especially during peak travel season. Booking your tickets and choosing your time in advance will give you more control and prevent you from waiting for the next train.

Don’t overlook the carriage and seat numbers on your ticket.

AREX Express uses fixed seating. You should check the correct carriage number and seat number before boarding to avoid sitting in the wrong seat and save time searching.

Don’t bring bulky luggage but don’t pack early.

Each carriage has its own luggage area, but if you have large luggage or are traveling in a group, you should board early to have enough space to pack and avoid having to move around a lot after the train gets crowded.
