The simplest route from Incheon Airport to Seoul Station
For most first-time visitors, AREX (the Airport Railroad Express) is the clearest rail connection between Incheon International Airport and Seoul Station. Two services run on the same line: a non-stop Express Train and a cheaper All-stop Train.
The short answer: the Express takes about 43 minutes and costs 13,000 KRW with a reserved seat. The All-stop takes roughly an hour for about 4,750–5,350 KRW and accepts a T-money card. Both run from around 05:20 until midnight.

| Journey time | About 43 minutes | About 59–66 minutes |
| Stops | None — direct | 13 intermediate stations |
| Seating | Reserved seat, luggage space, USB ports | Unreserved, commuter-style |

| Best for | Heavy luggage, tight schedule, late-night arrival fatigue | Budget travel, light bags, stops other than Seoul Station |

If you are travelling as a pair or family with suitcases, the price gap matters less than it looks: two Express tickets cost about 26,000 KRW, while two All-stop fares come to roughly 10,000 KRW. The real difference is whether you want a guaranteed seat after a long flight.
Step 1: find the airport transportation center
At both terminals, the AREX platforms are in the transportation center on Basement 1 (B1). After immigration and customs, follow the blue Airport Railroad signs down one level.
Terminal 1 and Terminal 2 are separate buildings about 15 minutes apart by shuttle, and each has its own AREX station. Check your boarding pass or the arrivals board if you are not sure which terminal you landed at — Korean Air, Delta, Air France and KLM generally use Terminal 2, and most other carriers use Terminal 1.
Incheon International Airport publishes terminal maps and an official Airport Railroad guide if you want to see the layout before you land.
Step 2: decide whether you need a T-money card
A T-money card is a rechargeable transit card used on subways, buses, and many taxis across Korea. You can tap it directly for the All-stop train, but the Express requires its own ticket, so a T-money card is not strictly necessary on arrival night.
That said, most visitors buy one within their first day anyway, since Seoul’s subway and bus network runs on it. Cards are sold at convenience stores inside the airport and at station vending machines, and topping up is done with cash at the same machines.
Keep some Korean won in small notes for your first day. Card acceptance is excellent in Seoul, but transit top-up machines are often cash-only.
Step 3: board AREX and allow time at Seoul Station
For the Express, buy a ticket at the counter or machine, then go to the dedicated Express platform. For the All-stop, tap in at the regular gates with a T-money card or a single-journey ticket.
Seoul Station is large and connects AREX, KTX intercity trains, Seoul Subway Lines 1 and 4, and a bus terminal. Walking between the AREX platform and the KTX concourse takes roughly 10 minutes with luggage.
If you are transferring straight to a KTX train — for example onward to Gyeongju or Busan — follow the KTX signs inside the station rather than exiting to street level first.
If you arrive late or have heavy luggage
- Late arrival: The last AREX departure is around midnight. If your flight lands after roughly 23:00, check the actual final departure before leaving the arrivals hall, and compare an airport limousine bus or a licensed taxi as a backup.
- Large luggage: The Express has dedicated luggage racks; the All-stop does not, and it gets crowded during commuter hours. Airport luggage delivery services can send bags to many Seoul hotels if you would rather travel light.
- Very early flights out: Working backwards, the first AREX leaves around 05:20, which is often too late for a 07:00 departure. Plan an airport hotel or an early limousine bus instead.
- Terminal 1 to Terminal 2: Allow an extra 8 minutes of rail time, or use the free inter-terminal shuttle bus.
Frequently asked questions
Is the Express train worth the extra cost?
For a first arrival with luggage, usually yes — it saves about 20 minutes and guarantees a seat. For a short-stay budget trip with a backpack, the All-stop does the same job for roughly a third of the price.
Can I use a credit card for AREX?
Yes. Ticket machines and counters accept major international credit cards, and Express tickets can also be booked online in advance.
What if I am going somewhere other than Seoul Station?
The All-stop train serves 13 intermediate stations including Hongik University Station, Digital Media City, and Gimpo Airport, several of which connect to other subway lines. If your accommodation is closer to one of those, taking the All-stop can be faster overall than riding to Seoul Station and backtracking.
Before you fly: a short checklist
