Welcome to Korea! One of the first things you’ll do after landing at Incheon International Airport (ICN) is figure out how to get to your destination. For most travelers, the AREX (Airport Railroad Express) is the fastest and most convenient option to travel from Incheon Airport to Seoul Station. This guide will help you navigate AREX like a pro, ensuring a smooth and efficient journey.
1. Understanding AREX: Express Train vs. All-Stop Train
AREX offers two types of trains, each with distinct advantages for your journey :
A. AREX Express Train (직통열차): The Fastest Route
- Speed & Stops: This is the fastest option, traveling directly from Incheon International Airport (Terminal 1 & 2) to Seoul Station without any stops. It’s the top choice if your primary goal is a quick, comfortable ride.
- Travel Time: Approximately 43 minutes from Terminal 1, and 51 minutes from Terminal 2 to Seoul Station.
- Comfort: Features comfortable, reclining seats, dedicated luggage racks, and onboard restrooms. You’ll feel like you’re on a high-speed train!

B. AREX All-Stop Train (일반열차)
- Speed & Stops: This train makes 13 stops between Incheon Airport and Seoul Station, similar to a regular subway line. It’s slower but connects you to various districts in Seoul.

- Comfort: Standard subway-style seating. Luggage space is limited to overhead racks or holding it in front of you. There are no restrooms onboard.
- Amenities: Wi-Fi is generally available but may require a Korean phone number for verification, which can be an issue for foreign visitors.
- Boarding: Boarding takes place on the general subway platform at both Incheon Airport terminals.
- Fare: Fares vary by distance, ranging from around 4,450 KRW to 4,750 KRW from Incheon Airport to Seoul Station, making it a more budget-friendly option. You can pay with a T-Money card or a single-use ticket.
