Incheon Airport to Seoul After Midnight: Night Bus or Taxi?
If you're working out how to get from Incheon Airport to Seoul after midnight, one fact settles most of it: the last AREX express toward Seoul leaves Terminal 1 at 22:48, and the all-stop train isn't far behind it. After that you have a night bus for ₩17,000–18,000 (about $13) or a taxi that starts near ₩70,000 (about $52) and climbs from there.
I went through the airport's own pages and the AREX timetable on Sept 8 to pin the times and fares below. Prices in dollars use the Sept 7 rate of roughly ₩1,345 to the dollar, so round accordingly if you're reading this months later.
The train: gone by 11 pm
The express timetable on the AREX site showed the last Seoul-bound run leaving Terminal 2 at 22:40 and Terminal 1 at 22:48 when I read it, arriving at Seoul Station at 23:31. The 23:00 sitting in the same table is the last train out of Seoul Station, which is easy to misread at 1 am; I did, on the first pass. The all-stop train runs a little later, but I couldn't get its full timetable to load, and the AREX site filters some late runs by an intermediate terminus, which suggests not all of them reach Seoul Station. Treat "past 11 pm" as no train.
That cutoff bites harder than it sounds. A flight that lands at 22:10 with a full immigration hall and checked bags to wait for is routinely on the kerb at 23:30. So the real question for most late arrivals is bus or taxi, and the answer depends on where you sleep tonight.
Four night buses, two platforms
Incheon Airport runs four late-night routes into Seoul, and the airport's Terminal 1 late-night bus page lists every departure. The Terminal 2 version of the page has the same routes leaving roughly 20 minutes earlier, because T2 is the first stop. This is the table for someone standing on the arrivals floor at 00:30.
| Route | Ends at | Useful stops on the way | T1 platform | Fare (adult) | T1 departures on the timetable (Sept 8) |
|---|---|---|---|---|---|
| N6701 | Dongdaemun Design Plaza | Mapo Stn (50 min), Seoul Station (60 min), Euljiro (65 min) | 3B | ₩18,000 | 23:50, 00:40, 01:40, 03:45, 04:40 |
| N6002 | Cheongnyangni | Hongdae (45 min), Four Seasons Hotel (60 min), Dongdaemun (75 min) | 6A | ₩18,000 | first 00:00, last 04:40 |
| N6000 | Gangnam Express Bus Terminal | Songjeong Stn, Yeomchang Stn, Express Bus Terminal (70 min) | 6A | ₩17,000 | first 00:10, last 04:20 |
| N6703 | Gwangnaru Station | Seorae Village, COEX (65 min), Jamsil Lotte World (70 min) | 3B | ₩18,000 | first 23:40, last 04:50 |
Two things the table can't tell you. The platforms are outside on the 1F arrivals level, and at 1 am in autumn the wind coming off the reclaimed land is properly cold, so don't stand out there in the T-shirt you flew in. And N6701 is the one to remember: it's the only night bus that stops at Seoul Station, and it's the one you want for Myeongdong, Jongno, or anything you'd reach from Line 1 or 4.
Buy the ticket before you board, at the booth or the ticket machine near the doors. The airport lists the Tmoney GO app as a third option for N6701 and N6002 only. I haven't tested whether those machines take a foreign card at 1 am, so bring some won from the arrivals-hall ATM just in case.
The gaps in the timetable are the catch. Miss the 01:40 N6701 and the next one is 03:45, two hours on a bench. If your bus is more than 90 minutes out, read the taxi section, then the last section.
What a taxi costs once the night meter kicks in
Seoul's standard taxi fare starts at ₩4,800 (about $3.60) on the meter, according to the airport's taxi page, and it's the surcharge schedule that matters after dark: 20% from 22:00 to 23:00, 40% from 23:00 to 02:00, then 20% again from 02:00 to 04:00. The meter adds it automatically. You'll also pay the expressway toll separately, and if you end up in an Incheon-plated cab the same page says a 30% out-of-area surcharge applies once it leaves Incheon (Seoul and Gyeonggi cabs list 20%).
So what's the number? The airport doesn't publish an estimate. The pre-booked International Taxi service, which is pitched at foreign visitors and needs 24 hours' notice, lists flat zone fares from ₩70,000 for the nearest Seoul zone up to ₩95,000 ($71); the 20% surcharges on its fare page apply to metered trips outside Seoul, not to those zone fares, and I couldn't pin down tolls from the page. Take those zone fares as the daytime floor for an ordinary metered cab too, and once the 40% night rate is on it, expect the meter to pass ₩100,000 ($74) to Gangnam. That last number is my arithmetic, not a fare anyone publishes.
The advice splits by group size. Travelling alone or as a pair, the bus wins outright: two N6701 tickets are ₩36,000 (about $27), a cab is three times that at least. A group of four with luggage is a different sum. Four bus tickets are ₩72,000, a taxi to Mapo or Seoul Station at 00:30 is plausibly ₩90,000–110,000 all-in, and it takes you to the door rather than to a stop 800 metres from your guesthouse. At that point the taxi is worth it, and I'd say so without hedging.
Getting one is simple. Standard taxis at T1 load from exits 5C, 6C and 6D on the arrivals floor; at T2 it's exit 7C. You don't need an app. If you do open Kakao T, blogs like Lacha report that registering a foreign card in-app is patchy, so set payment to "pay driver directly" and hand over your physical card in the cab. Show the driver your hotel address in Hangul on your phone; saying the neighbourhood name out loud ("Mapo-gu", "Gangnam") is enough to get moving.
For a New Yorker, the comparison is almost funny: New York's yellow-cab flat fare from JFK to Manhattan is $70 before tolls and surcharges, so the Incheon night bus costs less than the tip on that ride.
Landed at 2 am with a 3:45 bus? Just stay
You're allowed to dodge the whole problem: if your bus is two hours away, the airport is a perfectly good place to be. Darakhyu, the capsule hotel run by Walkerhill, has a branch on the first floor of the T1 Transportation Center and charges by the hour. I couldn't find a rate card on their site, so I won't guess a number.
If that's too much, the Sleeping in Airports guide to Incheon lists free rest areas and convenience stores that stay open through the night, and the arrivals floor at 3 am smells mostly of floor polish and coffee, which is more than most airports can say.
Then take the first bus of the morning, or wait for AREX, which restarts a little after 5 am (the express timetable showed 05:16 from T2 and 05:24 from T1). The all-stop fare is ₩5,350 (about $4) from T2 and ₩4,750 from T1, per Lacha's AREX guide. Honestly, that beats a ₩100,000 taxi ride you won't remember.
The night bus is fine. It is not comfortable, it is not fast, and nobody will help you with your bags, but at ₩18,000 it's the cheapest hour of your entire Korea trip. Take it unless you're four people or it's a two-hour wait.
Which terminal are you landing at, and what time? If you're stuck choosing between an 01:40 bus and a taxi, tell me the neighbourhood and I'll run the sums.
