Key City Stops
Seoul Station is the main hub — from there you can transfer to subway lines 1, 4, and the KTX high-speed rail to other Korean cities.
3 Practical Tips
- ✦
Buy or top up a T-money card at any convenience store in the airport — it works on AREX All-Stop, subways, and buses city-wide.
- ✦
Terminal 2 passengers (Korean Air, Delta, Air France, KLM) board AREX at T2 before T1 — the train continues through both terminals.
- ✦
Book AREX Express seats online in advance during Korean holidays (Chuseok, Lunar New Year) — sold-out trains are common.
FAQs
Is there luggage storage on the AREX train?+
Yes — AREX Express trains have overhead racks and designated luggage areas at the ends of each car. All-Stop trains have standard overhead racks.
Can I use a credit card to buy tickets?+
Yes, the kiosks accept Visa, Mastercard, and Korean credit cards. You can also pay cash (Korean won only).
How early should I arrive for my flight?+
Allow 90 minutes from central Seoul to the gate. Take the first AREX that gives you that window — the All-Stop is fine for most departures.
