Incheon Airport to Seoul: AREX, Night Bus and Taxi Fares

The best way from Incheon airport to Seoul depends on where your hotel is and what time you get through immigration. If you are headed to Seoul Station, the AREX Express takes 43 minutes from Terminal 1 and costs 13,000 won for an adult. After 11 p.m. the trains are basically done, so you’re looking at a night bus or a taxi.

First, check whether you landed at Terminal 1 or Terminal 2. Trains and buses leave at different times from each, and Terminal 2 is a bit farther from Seoul. The airport’s own advice is to allow 1 to 2 hours for immigration and baggage, so plan around the time you walk out of the arrivals hall, not the time you land.

Incheon airport to Seoul: five ways at a glance

The train details come from the official AREX pages, night buses and taxis from the Incheon Airport Corporation pages, and the limousine fare from the Airport Limousine fare table. There are many limousine routes, so look up the first and last bus for your route in the airport’s bus route search.

Beware outdated online travel guides quoting older base fares (9,500 won for Express or 4,150 won for All-Stop). Current official rates set Express admission at 13,000 won (discounted standard rate) and All-Stop at 4,750 won.

How long from Incheon airport to Seoul?

For Seoul Station, the Express is the quickest at 43 minutes from Terminal 1 and 51 minutes from Terminal 2. The all-stop train is 59 minutes from Terminal 1 and 66 minutes from Terminal 2. Night buses run 60 to 90 minutes depending on where they end. Taxi time depends on traffic, so I won’t promise a number.

AREX Express or all-stop?

The Express runs to Seoul Station without stopping, and your ticket comes with an assigned seat. The all-stop works like the subway: tap a transit card and ride, and it stops at every station. That means you can get off at Hongik University, Gongdeok or Digital Media City.

On the Express fare page, the regular fare is listed as 18,500 won from Terminal 1 and 19,100 won from Terminal 2, but what you actually pay is 13,000 won. The page doesn’t say how long that lower fare lasts, so check again when you buy. Children, seniors, people with disabilities and national merit holders pay 9,500 won.

Express tickets are sold at the AREX ticket office on the first basement level of each terminal’s transport center. The train has Wi-Fi and luggage racks, and you can ask for water. Trains come about every 30 to 40 minutes, so if one just left, the all-stop can actually get you there sooner.

For budget travelers and those heading to western Seoul, the All-Stop train serves as the most versatile route (Incheon airport transit breakdown). Beyond substantial fare savings, direct stops at major interchange hubs like Hongik University (Line 2 / Gyeongui-Jungang Line) and Gongdeok (Lines 5, 6, and Gyeongui-Jungang) eliminate redundant backtracking through Seoul Station (subway transit performance).

A single-use transit card costs 100 won more, and the 500 won deposit comes back at the station where you get off. If you’re staying a few days, buying a Tmoney card at the airport and tapping with it is less hassle.

Verify real-time operations on the AREX portal before departure, as periodic rail union labor actions can cause slight headway delays.

Incheon airport bus to Seoul: the limousine

If you have lots of luggage and your hotel is in Myeongdong, City Hall or around Gangnam, the limousine bus is easier than juggling trains. The airport’s route search lists Seoul routes such as 6001 (Dongdaemun), 6005 (City Hall), 6015 (Myeongdong), 6103 (Samseong), 6701 (City Hall, Gwanghwamun) and 6703 (Gangnam, COEX).

At Terminal 1, the Seoul buses leave from outside exits 3 to 7 on the first floor. At Terminal 2 it’s the bus terminal on the first basement level. The Airport Limousine fare table shows 17,000 won for an adult and 12,000 won for a child on central Seoul routes. That site doesn’t look like it’s been updated in a while, though, so confirm the exact fare for your route at the ticket booth.

Night buses after the last train

The last Express toward Seoul Station leaves Terminal 1 at 22:48. If you walk out of arrivals after that, a night bus is the realistic answer. I put the airport’s night bus timetables for the two terminals side by side, and each bus leaves Terminal 2 about 20 minutes before it leaves Terminal 1.

From Terminal 1 it’s about 70 minutes to Gangnam Express Bus Terminal, 90 minutes to Cheongnyangni and 60 minutes to Seoul Station. There’s also an N6703 to Gwangnaru Station, but check its time and fare in the airport timetable yourself. Note that legacy route N6001 to Seoul Station has been decommissioned from active service; rely on N6002 or N6701 for central district late-night connections.

You can’t pay for a night bus with cash or by tapping a transit card. Buy a ticket first at the ticket booth or a 24-hour self-service machine, and for N6002 and N6701 you can also use the Tmoney GO app (per the airport timetable). Staffed booths at Terminal 1 are open 05:40 to 22:20, with booth 4 closed from 1:30 a.m. to 3:30 a.m. At Terminal 2 they are open 04:00 to 24:00.

The airport’s English page for Terminal 2 night buses lists the same N6000, N6002 and N6701 routes with the same 17,000 and 18,000 won adult fares, which is a useful cross-check if you’re reading in English.

How late is too late for a train? The best English-language example I found is an older trip post from a traveler who landed around 10:30 p.m., written in 2016 and updated in 2019. They wrote, “We arrived at about 10.30pm, and the Express train was no longer available.” They ended up on the all-stop, which runs later, and called it “quite comfortable and hassle-free.” Trains and buses have changed since then, so use today’s times above.

I also read the comments under that Trazy guide, and the late-night question there is a familiar one. In 2019 a reader asked about a friend landing at 22:15 and expecting to clear customs around 23:30, and the only answer was a link to an airport taxi deal. That’s the gap the night bus table above is meant to fill.

Incheon airport taxi fare and late-night surcharges

With lots of bags or three or more people, a taxi can make sense. According to the Incheon Airport guide, the base fare is 4,800 won for a regular taxi and 7,000 won for deluxe and large taxis, and there’s no out-of-city surcharge for rides into Seoul or Incheon.

Regular taxis in Gyeonggi Province add 30% from 11 p.m. to 4 a.m., while deluxe and jumbo taxis add 20% from 10 p.m. to 4 a.m. Standard daytime taxi fares from Incheon Airport to downtown Myeongdong typically average 70,000 to 90,000 KRW, plus highway toll fees.

One thing stood out when I read the taxi page closely: each type of taxi has its own stand. At Terminal 1 regular taxis use 5C, 6C and 6D, deluxe 7C, large 8C, and International Taxi, which has foreign-language service, 4C. At Terminal 2 Seoul regular taxis use 7C, deluxe and large 7D and International Taxi 3C. The airport also warns about unmarked “call vans” that pretend to be taxis, so only get in at a marked stand.

Landing before dawn

If you step out at 4 or 5 a.m., the first AREX train is the cheapest option. The all-stop leaves Terminal 2 at 05:08 and Terminal 1 at 05:14, and the Express leaves Terminal 2 at 05:16 and Terminal 1 at 05:24. Before then, the 4 a.m. night buses are still running.

While 24-hour convenience stores and select cafe franchises operate overnight in both passenger terminals, retail options narrow substantially past midnight.
