Incheon Airport to Seoul by AREX: Fares and Stations

The AREX Airport Railroad is the rail link between Incheon International Airport and central Seoul. It has two kinds of train, and they differ in price, speed and how you buy a ticket. This guide explains both, lists the stations, and says where our sources stop.

Fares, travel times and ticket rules below were checked on 13 October 2026 on the Airport Railroad’s own website (airportrailroad.com). Train frequency and one travel time come from the Visit Seoul and VisitKorea websites, as noted. Fares change, and the official fare pages carry no revision date, so confirm the amount at the station before you travel.

Two Trains, Two Tickets

Express train (직통열차). It runs non-stop between Incheon Airport and Seoul Station. The Airport Railroad says the trip takes about 43 minutes from Terminal 1 and about 51 minutes from Terminal 2. You must buy a ticket before boarding, and seats are assigned.

All-stop train (일반열차). It stops at every station. The Airport Railroad gives about 59 minutes from Terminal 1 and about 66 minutes from Terminal 2 to Seoul Station, and says some trains take 2 to 6 minutes longer. You pay with a transportation card or a single-use card. Visit Seoul says all-stop trains leave every 5 to 10 minutes, and express trains every 20 to 40 minutes. That Visit Seoul page is undated, so we use it for frequency only.

Official Fares

| Train | Ticket | Adult fare | |—|—|—| | All-stop | Seoul Station to Terminal 1 (transit card) | 4,750 won | | All-stop | Seoul Station to Terminal 2 (transit card) | 5,350 won | | Express | Adult, discounted fare | 13,000 won | | Express | Regular fare, Seoul Station to Terminal 1 / Terminal 2 | 18,500 / 19,100 won | | Express | Child (6 to 12) | 9,500 won |

The all-stop fare is distance based. The Airport Railroad explains it as a base fare of 1,550 won for the first 10 km in the Seoul area, plus 100 won for each further 5 km from 10 to 50 km, with separate rules for the airport section. Children 6 to 12 and teenagers 13 to 18 pay discounted fares, and people 65 or older and children under 6 can ride free with the conditions on the page (for example, up to three young children per guardian).

If you use a single-use transit card, the Airport Railroad says it costs 100 won more for an adult, and a 500 won deposit is refunded at the arrival station.

Buying an Express Ticket

According to the Airport Railroad’s guide:

• You can book on its website or app. It says the site accepts many domestic and foreign credit cards and several mobile wallets, you can book up to two months ahead, and you must pay within 20 minutes to complete a booking.
• You can also buy at ticket machines at Seoul Station (B2), Terminal 1 (B1) and Terminal 2 (B1).
• Express boarding uses a QR code at the gate, and you should reach the platform at least 3 minutes before departure.
• Seoul Station’s City Airport Terminal is free to use.

Whether a transit card such as T-money works on the express train is not stated on the pages we read, so assume you need the express ticket.

The 14 All-Stop Stations

The Airport Railroad lists these stops, shown here in order from the airport, with transfers:

1. Incheon Airport Terminal 2
2. Incheon Airport Terminal 1
3. Incheon Airport Cargo Terminal
4. Unseo
5. Yeongjong
6. Cheongna International City
7. Geomam (검암, Incheon Line 2)
8. Gyeyang (Incheon Line 1)
9. Gimpo International Airport (Lines 5 and 9, Gimpo Goldline, Seohae Line)
10. Magongnaru (Line 9)
11. Digital Media City (Gyeongui-Jungang Line, Line 6)
12. Hongik University (Line 2, Gyeongui-Jungang Line)
13. Gongdeok (Lines 5 and 6, Gyeongui-Jungang Line)
14. Seoul Station (Lines 1 and 4, KTX, Gyeongui Line)

VisitKorea adds that the all-stop trip from Gimpo Airport to Seoul Station takes about 23 minutes. “Hongdae” is short for Hongik University, so this station name points to the Hongdae district in Mapo-gu. We did not confirm which exit is nearest to a specific place.

Which One Should You Take?

The sources give you the trade-off, not a single answer. The express train is about 16 minutes faster from Terminal 1 (43 versus 59 minutes) and runs non-stop to Seoul Station, but it costs 13,000 won at the discounted fare. The all-stop train costs 4,750 won to Seoul Station from Terminal 1 and lets you get off at Hongik University, Digital Media City or Gongdeok without a transfer at Seoul Station. If your hotel is near one of those stops, the all-stop train may be simpler. If it is near Seoul Station, the express train may suit you better.

What We Could Not Confirm

• First and last trains. The timetable page we read lists weekday departures from Terminal 1 toward Seoul Station from 5:14 to 23:56, but that table mixes express and all-stop trains. Check the timetable for your own train type.
• Fare revision date. The all-stop and express fare pages are not dated.
• Train frequency. The 5 to 10 minute and 20 to 40 minute intervals come from an undated Visit Seoul page, not from the Airport Railroad.
• Exits and walking routes at each station.
• Whether credit cards work at all-stop gates. The pages we read mention transit cards only.
