Compare the Main Options
Choose the service by final neighborhood, luggage and transfer count—not only by the fastest advertised journey.
| Option | Start | Destination | Transfers | Typical duration | Useful when |
|---|---|---|---|---|---|
| AREX Express | Incheon Airport Terminal 1 or 2 | Seoul Station | Direct, reserved-seat airport train | About 45–55 minutes | A direct airport-to-Seoul Station trip |
| AREX all-stop train | Incheon Airport Terminal 1 or 2 | Hongik University, Gimpo Airport and Seoul Station | No transfer for stations on the AREX line | About 55–70 minutes to central Seoul | Hongdae, Gimpo connections and intermediate stops |
| Airport limousine bus | Terminal bus stop | Selected Seoul hotel districts and major stops | Usually direct, but the stop may require a walk | Traffic-dependent | Large luggage or a destination close to a bus stop |
Practical Decisions
- For Hongdae, the all-stop train reaches Hongik University Station without changing trains.
- For COEX or Dongdaemun, compare the onward subway transfer with an airport bus serving the exact area.
- Confirm the terminal, first or last service and current ticket conditions on the operator’s website before travel.
