Terminal 1 / Terminal 2 timetable check
| Boarding point | Planning rule |
|---|---|
| Incheon Airport Terminal 2 | The train calls here before Terminal 1. Use the official AREX timetable for your date and selected Express departure. |
| Incheon Airport Terminal 1 | Choose the T1 timetable, not a T2 screenshot; the listed departure is later than the same train's T2 departure. |
| Seoul Station | Confirm the final Express departure and leave time for onward KTX boarding. |
AREX updates operating times, so this page links to the live official timetable instead of freezing a day-specific departure list.
AREX to KTX: luggage-friendly elevator route
Allow transfer margin and follow current station signage because elevator access and platform assignments can change.
AREX vs Bus vs Taxi Estimator
Select your Seoul destination for a planning-range comparison. Road times vary with traffic and rail totals exclude the final walk.
1. AREX Express vs All-Stop
| Feature | Express | All-Stop |
|---|---|---|
| Route | Non-stop airport terminals–Seoul Station | Every station, including Gimpo Airport and Hongik University |
| Typical planning time | About 43–51 minutes depending on terminal and current timetable | About 59–66 minutes to Seoul Station |
| Ticket | Dedicated departure and reserved seat; verify live fare | Transit-card tap or single-journey ticket; distance fare applies |
| Luggage | Dedicated storage and predictable seating | Commuter layout; can be crowded |
2. Buy and Use the Correct Ticket
At the airport machine, choose the train product first. Express passengers receive a dedicated ticket or QR credential for the selected service and should follow Express signs and gates. All-Stop passengers can tap a compatible transit card such as T-money or buy a subway single-journey card. Do not tap T-money at an Express-only gate and assume it covers the reserved train.
- Confirm Terminal 1 or Terminal 2.
- Select English and verify Seoul Station or the intermediate stop.
- Check the departure time, fare and gate printed on screen.
- Keep the ticket or QR available until the exit is complete.
3. Match the Train to the Hotel
Hongdae travelers normally benefit from the All-Stop train because Hongik University is an intermediate stop. Seoul Station hotels can compare the reserved Express with the lower-cost All-Stop. For Myeongdong or Gangnam, add the subway transfer, elevator route and final walk before deciding. A direct airport bus may be easier with large luggage even when its road time is longer.
