Choosing between AREX Express and All-Stop trains
The Airport Railroad (AREX) connects Incheon International Airport (T1 & T2) directly to Seoul Station. The premium Express Train is a non-stop service that costs ₩13,000 per adult. It guarantees a reserved seat, provides dedicated luggage racks, and has free Wi-Fi.
The All-Stop Train is a standard commuter subway line stopping at 14 stations. Using a T-money card, it costs ₩4,750 from Incheon Airport Terminal 1, and ₩5,350 from Terminal 2 to Seoul Station. There are no reserved seats, and it can be crowded during rush hours, but it is less than half the price.
For passengers heading to destinations on the route (like Hongik University or Gimpo Airport), the All-Stop train is actually faster or more convenient because the Express train does not make intermediate stops.
Quick answers
What is the City Airport Terminal benefit?
If you buy an Express Train ticket, you can use the In-town Airport Terminal at Seoul Station to check your baggage and complete immigration pre-clearance for free on the day of departure. This lets you skip the long check-in and security lines at Incheon Airport.
Are there discounts for the Express Train?
Yes. While the standard counter price is ₩13,000, you can get it for around ₩9,500 to ₩11,000 by purchasing discount vouchers in advance via travel websites like Klook, KKday, or the official AREX online reservation site.
Does the All-Stop Train cost more from Terminal 2?
Yes. Because Terminal 2 is further along the line, the All-Stop train fare is ₩5,350 (₩600 more than Terminal 1). This calculator uses the T1 base rate of ₩4,750 for comparison; please budget an extra ₩600 per person if you are departing from or arriving at Terminal 2.
