Two big bags? The limousine bus is kinder. Heading straight to Hongdae on a budget? Take the All-stop train. From Incheon Airport into Seoul you choose among the AREX Express, the AREX All-stop, airport buses, and taxis — and the fares and times do not line up in a single neat row.
Adult one-way figures below follow AREX passenger pages and Incheon Airport’s English transport guides (checked September 2026).
Express vs All-stop — what actually differs
AREX runs two products on the same corridor. The Express Train is nonstop between Seoul Station and Incheon Airport T1/T2 with a reserved seat. The All-stop (commuter) train calls at every AREX station, including Hongik University (Hongdae), and you ride with a transit card.
| Express | All-stop | |
|---|---|---|
| Stops | Seoul Station, T1, T2 only | All AREX stations (incl. Hongdae) |
| Time Seoul↔T1 / T2 | 43 / 51 min | About 59–66 min to Seoul Station (journey-dependent) |
| Adult fare | Selling fare KRW 13,000 (child / eligible discount KRW 9,500) | T1→Seoul KRW 4,750 / T2→Seoul KRW 5,350 (transit card) |
| Hongdae | No direct stop (transfer at Seoul) | T1 KRW 4,650 / T2 KRW 5,250 |
| Payment | Express ticket (online / app / machine / counter); seat reserved | T-money, WOWPASS, other transit cards; or single-use (+KRW 100, KRW 500 deposit) |
| Frequency | Roughly every 20–40+ min (check timetable) | More frequent commuter intervals |
Approved full fares are listed as KRW 18,500 (Seoul↔T1) and KRW 19,100 (Seoul↔T2), but the selling fare adults pay is KRW 13,000. Tapping T-money on an Express gate does not work.

Express — seats and last trains
Airport→Seoul: first departures T2 05:16 / T1 05:24, arrive Seoul 06:07. Last: T2 22:40 / T1 22:48 → Seoul 23:31. Seoul→airport last train: Seoul 23:00 (T1 23:43 / T2 23:51).

Express timetable is the place to recheck first and last trains on your travel day.
All-stop — Hongdae and Seoul Station fares
After the 28 June 2025 metropolitan base-fare revision, adult prepaid/postpaid card one-way fares are:

Airport bus — daytime direct and late night
For hotel stops along Gangnam or Myeongdong corridors with heavy luggage, an airport limousine bus is often the least stressful option. Per Incheon Airport’s English Seoul-area daytime table (stamp updated August 2024), Seoul ↔ ICN Direct is KRW 17,000 adult / KRW 12,000 child; via Gimpo is KRW 16,000 / 12,000. Recheck your exact route in Bus Search before you go — some lines differ.
From the airport, buy at a booth or kiosk (or the listed app). Do not assume a simple T-money tap covers outbound boarding. City→airport stops often take cards or credit.
| Product | Adult KRW | Child KRW | Notes |
|---|---|---|---|
| Seoul ↔ ICN Direct (daytime table) | 17,000 | 12,000 | airport.kr EN; Aug 2024 stamp |
| Seoul ↔ ICN via Gimpo | 16,000 | 12,000 | same source |
| Late-night N6000 | 17,000 | 10,000 | Gangnam Express Bus Terminal etc. |
| Late-night N6701 / N6703 | 18,000 | 12,000 | Seoul Station etc. |
Late-night buses matter after the last AREX. Sample times: N6000 T2→Gangnam EBT ~90 min; N6701 T2→Seoul Station ~80 min. Traffic can stretch that to 60–90+ minutes. Operators: Airport Limousine 02-2664-9898; Korea Airport Limousine 02-2667-0386.
See airport.kr late-night bus guide and the daytime fare article. Route lookup: Bus Search.
Taxi — meter vs zone flat fare
Standard mid-size taxi base fare for Seoul / Gyeonggi / Incheon is KRW 4,800. Deluxe / Jumbo (9-seater) base is KRW 7,000. Night surcharge (Seoul/Incheon standard): 40% 23:00–02:00, 20% 22:00–23:00 and 02:00–04:00; Gyeonggi standard often 30% 23:00–04:00. Highway tolls are extra — Yeongjong (Airport Expressway) passenger upper about KRW 3,200 one-way; Incheon Bridge passenger about KRW 2,000 from 18 December 2025.
Use taxis when you need door-to-door drop-off, but do not treat any single hotel total as fixed: destination, traffic, night surcharge, and tolls all move the meter. Use designated stands; ignore solicitation.
International Taxi sells Seoul zone flat fares (tolls included / no night surcharge on the zone product per operator English copy). Standard roughly KRW 70,000–95,000 by district; Deluxe/Large about KRW 100,000–140,000. Book about 24 hours ahead when you can. Phones 1644-2255 / 032-743-2357; booking site intltaxi.co.kr (EN).

Which option for which destination
Start with where you sleep. Seoul Station / City Airport Terminal (CAT) / reserved seat / punctual rail → Express. Hongdae / budget / frequency → All-stop. Heavy bags to a hotel bus stop on Gangnam–Myeongdong corridors → limousine. After the last AREX → night bus or taxi.
For two adults T1→Seoul Station: Express KRW 26,000 in 43 minutes; All-stop KRW 9,500 in about an hour; daytime direct bus KRW 34,000 and often 60–90+ minutes in traffic. Three or more people with hotel-front drop-off should compare limousine totals with International Taxi zone fares (~KRW 70k–95k Standard).
Seoul Station and Hongdae
Seoul Station alone: Express’s 43 / 51 minutes is the shortest train ride. A long Express wait can erase the ~15–16 minute official running-time gap versus All-stop. Final stop Hongdae: All-stop goes direct at T1 KRW 4,650 / T2 KRW 5,250. Express forces a transfer at Seoul Station.
One adult light on luggage to Hongdae usually saves about KRW 8,000 on All-stop versus Express. Two or three people who want seats should line up Express totals against limousine totals.
Gangnam, Myeongdong, hotel stops
Airport buses cut transfer hassle when the hotel sits on a published stop. Use ~KRW 17,000 adult daytime direct as a planning baseline, then confirm bay and fare in Bus Search the same day. Metered taxis often cost more once tolls and night surcharge stack. To cap the bill, book International Taxi’s zone product.
After the last AREX
If the last Express leaves T2 around 22:40, later arrivals use night buses (N6000 KRW 17,000, N6701/N6703 KRW 18,000) or taxis. Compare metered night+toll totals with the zone flat fare before you choose.
FAQ
Can I ride Express with T-money?
No. Express needs its own ticket and reserved seat. Only All-stop takes T-money, WOWPASS, other transit cards, or a single-use ticket.
Is Express always 30+ minutes faster?
Official train running times differ by roughly 15–16 minutes to Seoul Station. A long Express wait shrinks the real-world gain. Do not bank on a fixed “always 30+ minutes saved.”
Child fares?
Express selling fare: child / eligible discount KRW 9,500. Daytime direct bus child KRW 12,000; N6000 child KRW 10,000; N6701/N6703 child KRW 12,000. All-stop child/senior discounts follow transit-card rules and ID where required.
Does landing at T2 cost more?
All-stop card: T2→Seoul KRW 5,350 vs T1→Seoul KRW 4,750. Express selling fare stays KRW 13,000 for both terminals; time is 51 min (T2) vs 43 min (T1). From T2 you pay KRW 600 more on All-stop and ride eight minutes longer on Express.
Is the taxi total a fixed number?
Metered taxis start at KRW 4,800 and add distance, time, night surcharge, and tolls — totals swing. For a ceiling, use International Taxi zone fares (Standard about KRW 70,000–95,000).
Where do I buy tickets?
Express: airportrailroad.com, app, machines, Express customer centers. All-stop: transit card or station single-use. Buses: airport booth/kiosk/listed app; many city stops take card or cash.
