N6002 runs after midnight when AREX and Line 1 shut

N6002 is the night airport bus from ICN to Cheongnyangni, with a fare of KRW 10,000 and a run time that swings between 45 and 90 minutes depending on traffic on the eastern side of Seoul. It serves both T1 and T2, so you can board right after customs instead of dragging bags to a closed train platform.

The bus usually shows a headway of 30–60 minutes, so still treat it as a timed service, not a turn-up-and-go shuttle. Look for the N6002 sign at the airport bus stops labeled for Cheongnyangni on the arrivals level, and confirm “청량리” on the front LED before you tap or pay cash in KRW.

Once it leaves Incheon Airport, N6002 runs into eastern Seoul districts like Cheongnyangni, Seongbuk, and Junggok, which avoids a cross-city taxi from Gimpo or Seoul Station that can climb well past KRW 50,000 after late-night surcharges. Flyers on Korea forums mention this route specifically for arrivals hitting the doors around 23:30–01:00, when AREX and most subways are already done.

Be ready for a slow last leg: riders report the city section feeling “never-ending” thanks to constant stop‑start driving and traffic lights once you’re past bridges like Dongho Bridge. Compared with westbound airport night buses, this one spends more time on inner streets, so that 45-minute best case can easily slide closer to the 90-minute end after a long-haul.

Regulars don’t rely on Google Maps or Apple Maps here, since both often miss N-bus options and default to taxis. Instead, locals use Naver Map or Kakao Map to see live N6002 departures and updated stop lists, then compare that against an AREX all-stop train plus taxi from Seoul Station when landing before about 23:00.

Watch the stop announcements closely, especially after crossing into Seoul city limits, because riders warn that some N buses skip inner-city stops if nobody rings the bell. Hit the stop button one stop early for areas like Cheongnyangni Station so the driver actually pulls in, and keep a T-money or cash backup in case you miss and need a short KRW 5,000–10,000 taxi hop back.

Step-by-step from arrivals at ICN

1. After clearing customs at T1 or T2, follow “Bus” signs down to the airport bus stops on the arrivals level.
2. Find the stand that lists N6002 and “청량리” and check the posted timetable for the next departure within the 30–60 minute window.
3. Buy a ticket from the counter or pay directly on board with T-money or cash; the fixed fare is KRW 10,000.
4. Sit on the left side if you want fewer people climbing over you as passengers board at later stops near Songdo and the expressway ramps.
5. Track progress in Naver or Kakao Map, and press the stop button one stop before your target (for example, just before Cheongnyangni Station) so the bus actually pulls in late at night.

One last tip: screenshot the Korean stop name for your destination before flying, so if you do overshoot on N6002, you can hand it straight to a taxi driver for a quick correction ride.
