Seoul airport to city centre: AREX train, limousine bus and late-night transfers from Incheon and Gimpo

💡 The Short Version: For speed and reserved seating to Seoul Station, take the AREX Express Train (43 minutes non-stop, ₩13,000); you can book the seat online in advance. If staying in Hongdae or travelling on a budget, take the AREX All-Stop train (₩4,750 from Terminal 1, 59 minutes to Seoul Station; 50 minutes to Hongdae), which calls directly at Hongik University Station without changing trains. For door-to-door convenience with heavy luggage in Myeongdong or Dongdaemun, choose Airport Limousine buses 6015 or 6001 (₩17,000), which eliminate subway stairs. For arrivals after AREX closes at 23:50, board late-night buses N6000, N6001 or N6002 (₩10,000) or take an official metered taxi (₩70,000 to ₩90,000 including highway tolls). Or book ahead: reserved AREX Express Train tickets on Klookad{rel=“sponsored nofollow noopener”} cost less than station counters and let you pick your seats before landing.

Incheon Airport (ICN) vs Gimpo Airport (GMP)

Seoul is served by two international airports:

• Incheon International Airport (ICN): Located on Yeongjong Island in Incheon, roughly 50 to 60 kilometres west of downtown Seoul. Incheon handles the vast majority of long-haul international flights. It features two passenger terminals connected by a free 15-minute shuttle bus and the AREX rail line:
  • Terminal 1 (T1): Serves Asiana Airlines, international budget carriers and most global airlines.
  • Terminal 2 (T2): Serves Korean Air, Delta Air Lines, Air France, and KLM.
• Gimpo International Airport (GMP): Located within Seoul’s western municipal boundary, 15 kilometres from downtown. Gimpo primarily handles domestic flights (including shuttle flights to Jeju Island and Busan) alongside regional international flights from Tokyo Haneda, Osaka Kansai, Taipei Songshan, Beijing Capital and Shanghai Hongqiao.

Incheon Airport to central Seoul options compared

Prices are one-way adult fares in won.

Option 1: AREX Express Train

[!TIP] The Discover Seoul Pass includes a complimentary one-way AREX Express Train ticket, which can be redeemed either for your journey into Seoul or for your return trip back to Incheon.

Option 2: AREX All-Stop Train

The AREX All-Stop Train operates along the same railway tracks as the Express train, but functions as a commuter subway service calling at 14 stations.

• Routing: Connects Incheon Airport Terminal 2 and 1 to Seoul Station, stopping at Incheon International Airport Cargo Terminal, Unseo, Yeongjong, Cheongna International City, Geomam, Gyeyang, Gimpo Airport, Magongnaru, Digital Media City, Hongik University (Hongdae), Gongdeok, and Seoul Station.
• Journey time: 59 minutes from Terminal 1 to Seoul Station; 66 minutes from Terminal 2. The journey from Terminal 1 to Hongik University Station takes 50 minutes.
• Fare: ₩4,750 to Seoul Station from Terminal 1 and ₩5,350 from Terminal 2 with a T-money transit card; a single-journey card adds ₩100 plus a refundable ₩500 deposit. Hongik University Station costs ₩4,650 from Terminal 1.
• Seating: Longitudinal bench seating identical to standard subway carriages. Seating is unreserved; during peak commuter hours (07:30 to 09:00 and 17:30 to 19:30), carriages fill as the train approaches Digital Media City and Hongdae.
• Why Hongdae visitors should choose the All-Stop train: If your hotel is located in Hongdae (such as RYSE or L7 Hongdae, reviewed in our guide to hotels in Myeongdong and Hongdae), the All-Stop train delivers you straight to Hongik University Station without needing to travel into Seoul Station and backtrack on Subway Line 2.
• Operating hours: First train leaves Terminal 2 at 05:18 (Terminal 1 at 05:25); last train terminates from Terminal 2 at 23:32 (Terminal 1 at 23:39) for full service to Seoul Station, with late runs terminating at intermediate depots until 23:56.

Option 3: Airport Limousine Buses

Seoul’s network of Airport Limousine coaches offers comfortable point-to-point connections directly to prominent hotel clusters.

• Vehicle standard: 28-seat deluxe coaches with wide 2+1 reclining leather seats, generous legroom, air conditioning, and underneath luggage holds where the driver loads and tags your suitcases.
• Ticket price: ₩17,000 for standard adult single fare. Tickets can be purchased at staffed ticket booths or automated ticketing machines inside the terminal arrival halls and beside outdoor boarding bays. You can also tap a T-money card when boarding.
• Key routes for visitors:
  • Route 6015 (Myeongdong): Runs from Incheon Terminals 2 & 1 to Mapo, Gongdeok, Euljiro 4-ga, Hotel PJ, and Myeongdong Station. Ideal for travellers staying in Myeongdong or Euljiro.
  • Route 6001 (Dongdaemun): Runs to Yongsan Station, Samgakji, Seoul Station, Namdaemun Market, Myeongdong, and Dongdaemun History & Culture Park (DDP).
  • Route 6002 (Jongno & Hongdae): Runs to Hapjeong, Hongik University Station, Sinchon, Ewha Womans University, Jongno 3-ga, and Dongdaemun.
  • Route 6701 (K-Limousine - City Hall & Myeongdong): Carrier connecting Incheon to The Westin Josun, Lotte Hotel Seoul, Koreana Hotel, and Plaza Hotel for ₩18,000.

  • Terminal 2: Transportation Centre B1 indoor bus terminal bays 11 through 35.
• Pros and cons: Limousine buses eliminate carrying heavy luggage across multiple subway flights of stairs. However, highway and city road traffic can extend travel times from 65 minutes up to 90 or 100 minutes during weekday evening rush hours.

Option 4: Late-Night Night Buses (N-Buses)

If your flight arrives at Incheon Airport after 23:30, rail services will have closed. Dedicated late-night airport buses provide overnight transport into central Seoul.

• Schedule: Departures operate between 23:40 and 04:30 daily. Buses depart roughly every 45 to 55 minutes.
• Payment: Pay by tapping a loaded T-money card at the front door reader, or purchase a paper ticket at late-night ticket counters inside Terminal 1 (near Exit 4) or Terminal 2 (B1 Transportation Centre). Cash is accepted if exact change is tendered.
• Late-night subway connection: Because city subway lines do not operate between 00:00 and 05:30, arriving at Seoul Station or Express Bus Terminal on an N-bus requires taking a local late-night city bus (prefixed with “N”, such as the N15 or N16) or hailing a street taxi to your hotel.

Option 5: Taxis and private transfers

Official taxi ranks are located immediately outside the arrival halls on Level 1 of Terminal 1 and Terminal 2.

• Standard Taxis (Orange, Silver or White):
  • Run on a calibrated meter. A typical trip to central Seoul (Myeongdong, Jongno, Hongdae) costs between ₩70,000 and ₩85,000 during daytime.
  • Highway expressway toll charges (approximately ₩6,600 from Incheon) are added directly to the final fare meter.
  • Late-night surcharge: A 20% surcharge applies between 22:00 and 04:00 (increasing to 40% between 23:00 and 02:00 during peak nightlife hours).
• International Taxis (Orange or Black with “International Taxi” signage):
  • Drivers speak conversational English or Japanese.
  • Desk staff in the arrival hall (near Exit 4 in T1, and between Exits 2 and 3 in T2) assist with booking.
  • Fares to central Seoul are structured on flat zone rates: Zone A (western Seoul / Hongdae) is ₩65,000; Zone B (central Seoul / Myeongdong / Jongno) is ₩75,000; Zone C (eastern Seoul / Gangnam) is ₩85,000 to ₩90,000, including tolls.
• Deluxe Taxis (Mobeom, Black with gold trim):
  • Higher initial fare and distance rate, but no late-night surcharge. Trips to central Seoul typically range between ₩100,000 and ₩125,000.
• Ride-hailing apps: The primary taxi app in South Korea is Kakao T. Foreign travellers can set up the app using international mobile numbers and credit cards to hail regular or luxury cabs. Uber also operates in Seoul by dispatching licensed metered taxis (UT service).

[!WARNING] Never accept taxi offers from individuals soliciting inside the airport terminal building. Official metered taxis must only be boarded from the numbered curbside taxi stands outside the arrivals hall.

Arriving at Gimpo Airport (GMP)

Gimpo Airport is positioned close to Seoul’s urban core, making transfers quick and economical.

• Subway Line 9 (Gold Line): For travellers heading to southern Seoul and Gangnam. Board the Express Train (Geup-haeng) from Gimpo to reach Yeouido in 15 minutes, Express Bus Terminal in 27 minutes, and Sinnonhyeon (Gangnam) in 30 minutes for ₩1,700.

Practical airport arrival checklist

1. Exchange money or withdraw cash: Korean transit card kiosks and convenience store top-up machines only accept cash in won banknotes. Withdraw ₩30,000 to ₩50,000 from airport ATMs marked with “Global ATM” signage before leaving the arrivals concourse.
2. Collect your transit card: Purchase a T-money transit card (4,000–₩5,000 blank card) from airport convenience stores (GS25, CU, 7-Eleven) located on the arrivals level, or collect a pre-booked Discover Seoul Pass from designated airport redemption counters.
3. Pick up an eSIM or local SIM card: Telecommunications counters for SK Telecom, KT, and LG U+ operate booths in both terminals for picking up pre-ordered unlimited data eSIM profiles or physical SIM cards.
4. Choose your route: Review where to stay in Seoul to verify whether your hotel sits closer to a subway interchange station or an Airport Limousine bus stop.
