Incheon airport to Seoul: cheapest and fastest options compared
The cheapest listed option is the AREX All-stop train at ₩4,750, and the fastest rail option is the AREX Express at about 43 minutes nonstop to Seoul Station.
Cheapest bus fare of the 37 Seoul-bound limousine routes is ₩16,000, so the All-stop train saves ₩11,250 per person against it, and the train fare works out to roughly one third of the bus.
The Express, at about 43 minutes versus the All-stop’s about 66 minutes, saves about 23 minutes for ₩11,000 − ₩4,750 = ₩6,250 more.
The AREX fares and times shown here come from the AREX site as of April 2026, so confirm the current figure on arex.co.kr before you travel; bus fares are from the September 20, 2026 airport bus data feed.
If speed to Seoul Station matters most, the Express is the rail pick; if the hotel sits on a bus corridor, the door drop may beat both trains.
| AREX All-stop train (T-money) | ₩4,750 — about 28% of a ₩17,000 deluxe bus |
|---|---|
| AREX Express train, reserved seat | ₩11,000 — ₩6,000 less than a typical bus |
| Limousine bus, daytime (33 routes) | ₩16,000–₩18,000 |
| Night bus N-routes (4 routes) | ₩17,000–₩18,000 — ₩1,000–₩2,000 over the cheapest daytime fare |
| Regular taxi | ₩4,800 meter base (2023 fare model); total meter cost not published here |
AREX from Incheon Airport: All-stop vs Express
The All-stop train takes a T-money card and stops at 11 intermediate stations; the Express is a separate reserved-seat ticket and runs nonstop.
The line covers 14 stations from Incheon Airport Terminal 2/1 to Seoul Station, passing Gimpo Airport, Hongik Univ. and DMC on the way.
Tickets for the Express are sold online in advance or at the AREX Travel Center in the arrivals floor of each terminal, and a T-money card alone will not get you on the Express — a separate purchase is required.
The All-stop train runs commuter-style with standing room at peak times, while the Express guarantees a seat and carries dedicated luggage space and free Wi-Fi.
With large bags, the reserved seat tends to decide it; travelling light on a budget, tap the same T-money card used on Seoul subways and city buses.
Limousine bus: which route for which hotel area
Pick the route by hotel area: 6002 for Hongdae/Sinchon, 6009 for Gangnam/Sinnonhyeon, 6006 for Apgujeong, 6200 or 6705A for Jamsil, 6001 for Dongdaemun/Yongsan/Samgakji, and 6005 for City Hall/DMC.
Buses board at Terminal 1, 1F stops 3B–7A, or at Terminal 2, B1F stops 14–32, and each route’s stop is listed with it — for example 6002 boards at T1 1F stop 6A and T2 B1F stop 30.
Larger bags go in the bus hold at no per-bag fee, so the fare covers the luggage.
On most routes Terminal 2 is the first stop, so its departures run 15–20 minutes earlier than Terminal 1 — 6009 leaves T2 at 05:20 against T1 at 05:40.
Tickets are sold at arrivals booths (T1 1F near gates 4 and 9, T2 1F) and on most routes the driver takes card payment at the stop.
Per-route ride times are not published — only first and last departures and the stop list — so leave slack before any fixed evening plan.
Landing after midnight: night buses and taxis
After midnight the only public options are four night N-routes from Terminal 1, departing 00:30–01:05, or a taxi; the last AREX train leaves before 23:00.
N6701 runs toward Dongdaemun at ₩18,000 (last T1 departure 00:40) via Seoul Station, Euljiro and DDP; N6703 toward Gangnam at ₩18,000 (01:05) via Samsung Station and Jamsil; N6000 toward Gangnam Express Bus Terminal at ₩17,000 (00:50); and N6002 toward Cheongnyangni at ₩17,000 (00:30) via Hongik Univ.
Station and Gwanghwamun.
The night fare runs ₩1,000–₩2,000 over the cheapest daytime route.
If the hotel is not on an N-route corridor, head for the taxi stand — at T1 1F around gates 4C–8C, at T2 1F — with a 20% late-night surcharge applying between midnight and 4:00 a.m.
Taxi from Incheon to Seoul: when it makes sense
A taxi makes sense for groups of 3–4 with heavy luggage or for arrivals outside bus hours; the meter starts at ₩4,800 (2023 fare model) and the ride to central Seoul takes about 60–70 minutes in normal traffic.
No total metered fare table is published in the data used here, so compare the meter against the bus benchmark: at ₩17,000 per person, three bus seats cost ₩51,000.
The meter usually totals more than that, but the fare splits fairly across 3–4 people and drops you at the door, and it can exceed 90 minutes at peak hours.
Eight-seat jumbo taxis at the designated stands suit groups of 5–8 with luggage.
Before anything else, check the arrival terminal and landing time — Terminal 2 buses leave 15–20 minutes earlier than Terminal 1, and past midnight only the four night buses or a taxi run.
With one bag and no deadline I would take the AREX All-stop train on T-money, because the fare gap over a shared taxi is too wide to justify the door-to-door ride.
What I check first is the landing time, since it alone decides between the train and the night buses.
