⚠️ Gimpo's rail hub is in the basement: the AREX All-Stop reaches Seoul Station in ~20 min (and Incheon in ~30 min), Line 9 is fastest to Gangnam — board the EXPRESS (red), not the local — and Line 5 heads to the centre (T-money card). Because GMP is close in, taxis and Kakao T/Uber are affordable (unlike Incheon). Don't take the “Goldline” — it serves Gimpo city, not Seoul. The terminal closes ~midnight–05:00. Confirm you're at GMP, not Incheon (ICN).
Gimpo International Airport
Seoul, South Korea
Gimpo is close to central Seoul (~15–24 km), so it's fast and cheap to leave. The subway/AREX hub is in the basement: the AREX All-Stop reaches Seoul Station in ~20 min (and Incheon in ~30 min), Line 9 Express (red) is fastest to Gangnam (~38 min), and Line 5 heads to the centre — all on a T-money card. Because GMP is close in, taxis and Kakao T/Uber are affordable (~30–45 min door-to-door), unlike from distant Incheon (Uber Black meets at Gate 1 International / Gate 6 Domestic; regular Uber/International Taxi at Gate 3, International only). Airport Limousine Buses run to major hotels if you have heavy bags. Confirm you're at GMP, not Incheon (ICN).

Pickup Guidance
Rideshare
Kakao T is the local ride app; Uber also works (dispatching licensed taxis, with Uber Black). Per Uber's GMP guidance, Uber Black meets at Gate 1 (International) / Gate 6 (Domestic), and regular Uber and the International Taxi are at Gate 3 (International only). Have your destination in Korean or pinned.
Taxi
Ranks outside arrivals at both terminals, 24/7. Color-coded — orange/silver/white = standard; black = deluxe/premium (pricier); international taxis have English-speaking drivers (~20% more). To central Seoul ~30–45 min; a late-night surcharge applies after ~22:00–23:00. Card/T-money accepted.
Shuttle
Airport Limousine Buses run from platforms outside arrivals (International near Gate 1, platforms 6–7; Domestic near Gate 6) direct to major Seoul districts and hotels (Gangnam, Myeongdong, Jamsil), ~60–80 min, luggage stored.
Transit
Gimpo Airport Station is on the basement level. Line 9 — board the Express (red) for Yeouido/Gangnam (~25–38 min); Line 5 for the centre; AREX All-Stop to Seoul Station ~20 min (and Incheon ~30 min). Tap T-money/Cashbee or buy a single ticket. Do NOT take the Gimpo Goldline — it serves Gimpo city, not Seoul.
Private Transfer
Pre-booked private transfers meet you at arrivals with a name sign — useful for a very late/early arrival, since the terminal closes ~midnight–05:00.

Local Tips
- On Line 9, board the Express (red) train, not the local — it skips half the stations and is the fastest way to Yeouido/Gangnam.
- Taxis and rideshare are genuinely affordable from GMP (unlike Incheon) because the airport is close in — a comfortable option with luggage or at night. Use Kakao T or Uber for app booking and language support.
- AREX is the best GMP↔Incheon connector (~30 min) if you're transferring between Seoul's two airports — far more reliable than a traffic-bound bus or taxi.
- Get a T-money/Cashbee card (convenience stores, station machines) — it works on Line 5, Line 9, AREX, buses, and taxis, with transfer discounts.
- Don't take the “Goldline” expecting central Seoul — it serves Gimpo city; use Line 5/9 or AREX for Seoul.
- The terminal closes ~midnight–05:00 — for a very late/early arrival, a taxi/Kakao T or pre-booked transfer is your option (you can't wait inside overnight).
Tarmyq local tip
Gimpo's the “speed” airport — it's right in the city, so you've got options. The subway station's in the basement: take the AREX to Seoul Station (~20 min), or Line 9 for Gangnam — but make sure you board the red Express train, not the local. And unlike Incheon, a taxi or Kakao T from Gimpo is genuinely affordable, so it's a fine choice with luggage. Just don't hop on the “Goldline” — that one heads into Gimpo city, not Seoul.
