Incheon Airport to Seoul: Train, Bus, or Taxi?

Taxis come up in 362 of the 1,569 threads, the train in 287, the limousine bus in 222, each thread counting once per option it names, so the numbers overlap. 612 name at least one of the three modes — the two AREX trains count as one — and 957 name none. A count only tells us an option came up. Taxis lead the count here; the train leads the list above.

Both leave from the Transportation Center on basement level 1 of each terminal, but they are different products. The express runs nonstop to Seoul Station, the city's main rail terminal, on its own ticket, with an assigned seat and a QR code for the gate. The all-stop is the commuter version, paid by tapping a T-money card, Korea's rechargeable transit card, or a single-journey card from the station machine, 100 won above an adult's card fare with a 500 won deposit back at the far end. Two tickets, two ways through the gate — one traveler describes them as separate entrances.

“airport express and the all-stop train have separate entrances, so it’s pretty hard to mix them up!” (as written)

The train goes wrong when Seoul Station isn't where you're sleeping, and the last leg with all your bags is where its time advantage goes. One answer to an asker staying elsewhere:

“Taking the AREX to Seoul Station then to Janghanpyong would involve two transfers.... so no, the limo is your best bet” (as written)

The operator's pages say nothing about suitcases. One reply describes the carriages:

“There are small luggage storage sections in each carriage (usually near the end of the carriage).” (as written)

Limousine bus and airport bus are two names for the same thing, and luggage rides in the hold instead of up subway stairs.

“Limousine bus is the way to go...way easier than the subway with heavy luggage” (as written)

Two companies run the Seoul routes. KAL Limousine has 6701 (City Hall, Gwanghwamun), 6702 (Seoul Station, Dongdaemun), 6703 (Gangnam, COEX) and 6705A (Jamsil), leaving the terminals between 05:00 and 23:15, each route on its own window. Airport Limousine has 6001 (Dongdaemun, Myeongdong, Seoul Station), 6002 (Cheongnyangni, Sinchon, Hapjeong) and 6015 (Chungjeongno, Gongdeok, Mapo), and publishes its times per route; anything else is on the airport's route finder (airport.kr bus routes).

Buy at the booth before you board — at Terminal 1 inside by exits 4 and 9 and outside near exits 4, 6, 7, 8, 11 and 13, with Seoul buses loading outside exits 3 to 7. At Terminal 2 the booth and the Seoul stands are both in the basement Transportation Center, and since March 2026 a ticket is required there before boarding. Three Terminal 1 routes are the exception. Routes 6001, 6002 and 6015 board first-come, first-served, cash or transit card at the door. KAL sells airport departures at its booths and machines only, and what those take is not published, so land with won.

Seoul's official city guide puts a standard taxi into the city at 31,000–58,500 won on the meter plus a 7,900 won expressway toll, 40 to 100 minutes depending on your destination (english.seoul.go.kr). The night surcharge lands on top, 20% from 22:00, 40% from 23:00 to 02:00, 20% again until 04:00. Forty percent on top of a 58,500 won meter is about 82,000 won, toll still extra.

Solo, that is a splurge; for three or four with bags it competes with that many bus seats. The meter is per car, so four people pay one fare, and that 31,000–58,500 range is a standard cab's. Deluxe and jumbo cabs start at 7,000 won against 4,800, a jumbo seats nine, and their night surcharge is a flat 20% from 22:00 to 04:00. The airport publishes no jumbo total and no standard-cab capacity, so a family with four big cases can't price the ride in advance. Ranks are marked by grade. Terminal 1 puts standard cabs at 1F bays 5C, 6C and 6D and the other two at 7C and 8C. Terminal 2 puts standard at 7C and deluxe at 7D, with no jumbo bay listed, so a group there queues at 7D. The airport warns that call vans posing as taxis solicit illegally and overcharge, so walk past anyone offering a ride inside the building.

Start the clock at immigration, which the airport tells arriving passengers to allow one to two hours for.

The last express out is 22:48 from Terminal 1 and 22:40 from Terminal 2, and the first is 05:24 from Terminal 1 and 05:16 from Terminal 2, with 26 airport departures a day, 25 to 65 minutes apart and most often 40. We couldn't confirm the all-stop's first and last trains, so check the operator's timetable (AREX timetable). Three moves work after that.

1. A taxi, with the surcharge above, 40% on the meter from 23:00 to 02:00 and 20% until 04:00.
2. A late-night airport bus, if one covers your district. Four run into Seoul, boarding at both terminals, Terminal 2 first and Terminal 1 twenty minutes later, five or six runs a night (airport.kr night buses). Ten more head into Gyeonggi, the province around Seoul, between 00:10 and 04:10.

3. Sleep by the airport. Terminal 1 has a 24-hour capsule hotel, Darakhyu, in the basement Transportation Center and a Transit Hotel on 4F near Gate 11. Unseo is two all-stop stops from Terminal 1, and one traveler asked about a last night there:

“Taxi takes 15 minutes costing 15,000 KRW from Unseo Station. AREX trains do not operate before 530am.” (as written)

The 530am there is the commenter's figure for Unseo; the terminals' own first express is earlier.

Inside the terminals only Terminal 1 has a hotel, and the free shuttle to it, from Gate 7 on Terminal 2's third floor, runs 04:30 to 23:35. Land later at Terminal 2 and the hotel is out of reach until 04:30, though the night buses board there too and Unseo still works by taxi.

1. Check which terminal you are in. Your e-ticket names it and the airport's airline list (airport.kr) confirms it before you fly; the train times, the all-stop fare and the boarding spots all differ. They are separate buildings, joined by that free shuttle.
2. Buy and load a T-money card at a convenience store or a subway station. The card is 3,000 won and pays for the all-stop, the subway and city buses; our T-money guide has the rest.
3. Pick from the table. A bus route near your hotel means the ticket booth, then the stands; otherwise the Transportation Center on B1. Past the last train, the taxi rank or a night bus.
4. Taking the train? On the train level, the express machine issues a QR code for the gate; the all-stop takes a T-money tap.
5. At Seoul Station, finish by subway or from the taxi rank outside. Off the bus, your stop is the last leg; in a taxi, show the address in Korean.
