Missed the last AREX at Incheon? A night bus is still running

Last verified

By Seungyeop Yeom ·

If your flight lands at Incheon late, check the timetable for your own terminal before you assume the train has gone. The two terminals do not stop at the same time: on the operator’s published schedule the last express to Seoul Station leaves Terminal 2 at 22:40 and Terminal 1 at 22:48, and the all-stop train runs later still. If the train really has gone, four numbered night bus routes and taxi stands keep working until somewhere between 04:20 and 04:50, depending on which route or taxi type you pick.

This is the order to check things in, and what each option actually costs.

First, check whether the train is really gone

Incheon Airport runs two AREX trains to Seoul Station: an express and a regular (all-stop) service. They stop at different times, and each terminal has its own last departure, so a single “last train” figure copied from a travel blog is the wrong thing to plan around.

  • AREX express: T1 to Seoul Station in 43 minutes, T2 to Seoul Station in 51 minutes, 11,000 KRW one-way. The operator’s timetable gives the last Seoul-bound departure as 22:40 from T2 and 22:48 from T1. The 23:00 you may see quoted is the last train in the other direction, out of Seoul Station.
  • The AREX regular (all-stop) train takes longer: T1 to Seoul Station in 59 minutes, T2 to Seoul Station in 66 minutes, and it costs 5,100 KRW (4,500 KRW if you tap a transport card instead of buying a paper ticket).

The all-stop train runs later than the express. The operator’s timetable lists departures from Terminal 2 in the 23:00 hour at 23:13, 23:32 and 23:50. It does not publish where each of those trains terminates, and late-night services on this line do not all run the full distance, so the 23:50 may stop short of Seoul Station. Read the destination on the platform display rather than assuming.

So: if you are off the plane before 23:30, go and look at the departure board before you decide you need a bus. The board is the only thing that knows what is actually running tonight.

If the train really is gone: four night bus routes

Incheon Airport runs four numbered night bus routes (N-buses) after the trains stop. Each one goes to a different part of Seoul, so which one you want depends on where you’re staying, not on price.

Route Where it goes Adult / child fare Runs
N6000 Gangnam Express Bus Terminal 17,000 KRW / 10,000 KRW 00:10–04:20
N6002 Cheongnyangni, via Hongdae-ipgu, Gwanghwamun, Heunginjimun 18,000 KRW / 12,000 KRW 00:00–04:40
N6701 DDP, via Mapo Station, Seoul Station, Euljiro-ipgu 18,000 KRW / 12,000 KRW 23:50–04:40
N6703 Gwangnaru Station, via Seorae Village, COEX, Jamsil Lotte World 18,000 KRW / 12,000 KRW (10,000 KRW / 6,000 KRW if you board at Songjeong Station) 23:40–04:50

All four routes serve both T1 and T2. These fares and route descriptions reflect a route reorganization that took effect on 2025-08-01: N6000 was extended from a T1-only route to cover T2 as well, N6002 absorbed an old overlapping route and picked up the Hongdae-ipgu and Gwanghwamun stops, and N6703 was extended out to Gwangnaru Station. If you’re reading an older guide that quotes lower fares or says N6000 only serves T1, it’s describing the route before that change.

Who should take which bus (or skip the bus entirely)

  • If you land after 23:38 from T1 (or 23:32 from T2) → the regular AREX train is gone for the night, so you’re choosing between a night bus and a taxi.
  • If you’re staying near Gangnam or the Express Bus Terminal → take N6000; it goes there directly for 17,000 KRW.
  • If your hotel is in Hongdae, near Gwanghwamun, or close to Cheongnyangni → N6002 covers that whole corridor in one route.
  • If you want to buy your ticket from your phone before you land → N6701 is the only one of the four that’s bookable through the T-money GO app; the fare and route (DDP, Mapo, Seoul Station, Euljiro-ipgu) are the same either way.
  • If you’re headed to COEX, Jamsil Lotte World, or Gwangnaru, and you can get yourself to Songjeong Station → boarding N6703 there costs 10,000 KRW instead of 18,000 KRW.
  • If none of the four routes pass near where you’re staying, or you’re a group of three or more with a lot of luggage → skip the bus and go straight to a taxi stand.

The taxi you flag down is not the only taxi

Seoul’s taxi fares changed on 2023-02-01, and the airport’s own taxi guide lists a night-surcharge structure that most first-time visitors don’t know exists. There are three taxi types waiting outside arrivals, and they are not priced the same way at night.

Taxi type Daytime starting fare Late-night starting fare Night surcharge
Regular (medium) 일반(중형) 4,800 KRW (first 1.6km) 5,800 KRW (22:00–23:00 and 02:00–04:00) / 6,700 KRW (23:00–02:00) 20% (22:00–23:00), 40% (23:00–02:00), 20% (02:00–04:00)
Deluxe / large 모범·대형택시 7,000 KRW (first 3km) 8,400 KRW (22:00–04:00) Flat 20% for the whole 22:00–04:00 window
International / smart 국제택시/스마트택시 Flat zone fare for Seoul destinations Same flat zone fare None, excluded from the night surcharge

The numbers in this table are starting fares, not full trip totals. The rest of the fare still runs on the meter based on distance and time, and that per-kilometer rate isn’t part of what’s published here. What the table does tell you is the shape of the pricing: a regular taxi’s surcharge jumps to 40% between 23:00 and 02:00, while a deluxe or large taxi’s surcharge stays flat at 20% across the entire night window, and an international or smart taxi runs on a fixed zone fare with no night surcharge at all. That’s the opposite of what the sticker price suggests. The “expensive-looking” taxi can end up costing less than the ordinary one if your ride falls in that 23:00–02:00 window.

Two calculations worth doing before you leave arrivals

If you were hoping to catch the express and it’s already gone, the loss is smaller than it looks. Two adults taking the regular train instead of the express pay 5,100 KRW each instead of 11,000 KRW each. Combined, that’s a saving of 11,800 KRW for the pair.

If you’re a family taking N6002 into the city (two adults and two children, say, heading toward the Hongdae/Gwanghwamun corridor), the bus fare alone comes to 60,000 KRW total.

That’s a fixed, known number before you’ve left the terminal, which is the main argument for the bus over a taxi when a route actually goes where you’re staying. You know the exact fare in advance, instead of watching a meter run through a 40% surcharge band you can’t calculate from arrivals.

What to actually watch for

The express stops running well before the regular train does: at Incheon this gap runs from 22:40 (T2’s last express) to 23:32/23:38 (the regular train’s last departures). Check only the express timetable, and you may conclude the AREX is finished while a working train sits on the platform.

It’s the same train, but it reaches T2 first (last departure 23:32) and T1 six minutes later at 23:38, so T2’s cutoff comes six minutes before T1’s. Use T1’s time as your cutoff at T2, and you can arrive at the platform after it’s already gone.

Unlicensed drivers work arrivals. In a case dated 2025-03-23, authorities caught a group of people who had recruited foreign tourists through social media and were running unregistered paid transport in rental and private cars, overcharging passengers well above the metered fare. Use the marked taxi stand or the night bus stop, not someone who approaches you inside the terminal.

N6000 and N6002 sell tickets at the counter only; you can’t book either one in advance through an app. N6701 is the exception: it’s bookable through T-money GO if you’d rather have the seat locked in before you land.

The taxi that looks pricier can be the better deal at night. As the table above shows, deluxe, large, and international taxis skip the 40% surcharge that hits regular taxis between 23:00 and 02:00. If you’re arriving in that window, don’t rule them out on sticker price alone.

Step by step

  1. The moment you clear immigration and baggage claim, check the clock against the regular AREX cutoff for your terminal: 23:32 at T2, 23:38 at T1. If you’re inside that window, go straight to the AREX platform. You can still make the regular train.
  2. If you’ve missed it, head to your terminal’s night bus stop and check the departure board for N6000, N6002, N6701, and N6703, then pick the one that runs closest to where you’re staying, using the route table above.
  3. Buy your ticket at the counter for N6000 or N6002, or use the T-money GO app in advance for N6701. For N6703, decide whether it’s worth getting yourself to Songjeong Station for the lower fare.
  4. If no route serves your area, or you’re a larger group, walk to the taxi stand and choose based on the time: a regular taxi if you’re outside the 23:00–02:00 surcharge band, a deluxe/large or international/smart taxi if you’re inside it.
  5. Confirm the current schedule before you fly, since airport transit timetables do get revised, so check the official pages below rather than a blog post:

Where to book

Nothing above needs an advance booking beyond what’s already listed. You buy the AREX ticket at the machine or gate, you buy night bus tickets at the counter for N6000 and N6002 (or through T-money GO for N6701), and taxis are hailed at the marked stand outside arrivals, not reserved ahead of time. The one thing worth arranging before your flight lands is a pre-booked airport transfer, so you skip all of the above and have a driver already waiting when you clear customs. If that sounds better for a late arrival than working out bus routes at 1 a.m., compare transfer options below.
