Incheon International Airport (ICN) Guide
Quick summary
Incheon is Seoul's main international gateway, split across Terminal 1 and the newer Terminal 2, connected by a free shuttle bus. The AREX airport railroad runs both an Express and an all-stop line to Seoul Station, and the airport is regularly ranked among the world's best.
Terminals at ICN
Incheon has two passenger terminals about 15 km apart. Terminal 1 is the original hub used by Asiana, most foreign carriers and low-cost airlines, while Terminal 2 (opened 2018) serves Korean Air and its SkyTeam partners including Delta, Air France and KLM. Always confirm your terminal before arriving, as they are not walkable from each other. A free shuttle bus runs between them roughly every 5-12 minutes, taking about 15-20 minutes, boarding at the 3rd-floor departures level (near Exit 8 at T1 and between Exits 6-7 at T2). The AREX airport railroad and airport buses also stop at both terminals. Each terminal has its own airside transit area, so allow a comfortable buffer - at least 2-3 hours - if your itinerary makes you switch terminals between flights.

🚆 Getting to & from the airport
The AREX (Airport Railroad Express) is the fastest fixed-price link to central Seoul. The nonstop Express train runs to Seoul Station in about 43 minutes from Terminal 1 (about 51 from Terminal 2) for roughly ₩13,000, with reserved seats and in-town check-in for some airlines. The cheaper All-Stop (Commuter) train costs around ₩4,000-5,000, makes local stops and connects into the Seoul subway network. Airport Limousine buses run to hotels and districts across Seoul (about ₩10,000-18,000). Taxis to central Seoul run roughly ₩60,000-90,000 and take 60-70 minutes depending on traffic; standard (orange/silver) and 'deluxe' black taxis both queue outside arrivals. Ride-hailing via Kakao T is widely used, and the KTX high-speed rail also serves the airport station for travel beyond Seoul.

Insider tips
- Double-check whether you fly from Terminal 1 or Terminal 2 before leaving home - they are 15 km apart and only linked by a free ~20-minute shuttle bus.
- The AREX Express is fastest to Seoul Station, but the All-Stop train is a fraction of the price if you're not in a hurry.
- Buy or reload a T-money card to tap through the All-Stop train and Seoul's subway and buses seamlessly.
- For a 5+ hour layover, sign up for a free Incheon Transit Tour at the desk near the arrivals area to see Seoul or nearby sights.
- Use the airside transit hotels (bookable in 6-hour blocks) if you need genuine sleep between flights.
