If you’ve just landed at Incheon International Airport (ICN) and want to get to Seoul quickly,
the AREX (Airport Railroad Express) is the fastest, easiest, and most affordable option.
Here’s a complete guide to using the AREX — including where to board, what to expect, and important traveler tips.
1. What Is the AREX Train?
The Airport Railroad Express (AREX) connects Incheon Airport (Terminals 1 & 2) with Seoul Station in the city center.
It’s clean, comfortable, and equipped with Wi-Fi, USB charging ports, and luggage space.
There are two types of trains:
- Express Train: Direct service (non-stop) to Seoul Station.
- Duration: 43–50 minutes
- Fare: 9,500 KRW (≈ $7 USD)
- All Stop Train: Stops at every station (e.g., Hongdae, Gimpo Airport).
- Duration: 55–60 minutes
- Fare: 4,750 KRW (≈ $3.50 USD)
💡 Tip: If you’re staying in Hongdae (Hongik Univ.), the All Stop Train is your best choice.
2. Boarding Tips & Entry Timing
You can enter the platform only 30 minutes before your train departure time.
Even if you scan your QR code earlier, the gates won’t open.
🚻 Important: There are no restrooms beyond the gate area,
so make sure to use the restroom before scanning your ticket QR code.
3. Getting Between Terminals
If you’re arriving at Terminal 2, you can take the free shuttle bus to Terminal 1,
where most AREX services depart.
The shuttle runs every 5–8 minutes, and travel time is about 10 minutes.
4. Onboard Experience
The AREX Express Train is designed for comfort:
- Luggage space: Holds up to two 28-inch suitcases per passenger.
- USB ports & Wi-Fi: Every seat has USB charging and free Wi-Fi.

5. Where to Buy Tickets
You can purchase tickets in several ways:
