30-second answer
Take the AREX All-Stop Train for the most predictable public-transport trip from Incheon Airport to Gimpo Airport. It serves Gimpo Airport Station without a line change. Do not board the AREX Express, which runs toward Seoul Station without serving Gimpo Airport.
Use a taxi when the train has stopped, your group has too much luggage for rail, or a mobility need makes the station route impractical. A bus can work when its current departure suits your flight, but rail avoids road congestion.
This is an airport-to-airport transfer. Check your entry path in the Korea Visa Navigator. Before leaving ICN, confirm whether you must collect bags, which Gimpo terminal you need and the receiving airline’s check-in cutoff.
VERIFY: Add current times and fares from T1 and T2, a tested ICN platform route and the full Gimpo station-to-check-in walk.

Incheon Airport’s FAQ describes rail and bus as common direct connections between the airports. Schedules and operating patterns can change, so use the Airport Railroad Guide and current operator data on the travel day.
Before you leave Incheon Airport
Check these five items:
- Your arrival terminal at ICN: T1, T2 or the Concourse.
- Whether checked baggage transfers or must be collected.
- Your departure building at Gimpo: domestic or international.
- The new airline’s check-in and bag-drop cutoff.
- Korean entry requirements for your passport and itinerary.
Airlines, not route blogs, control through-checking and connection acceptance. Separate tickets can require a full entry, baggage and check-in process. If the first flight is delayed, contact the onward airline before traveling.
No single minimum connection time fits all itineraries. VERIFY: Provide scenario ranges only after airlines and a local editor review them. Label every range as planning guidance, not a protected connection.
AREX All-Stop Train: the straightforward route
Follow signs for Airport Railroad or Transportation Center from the arrivals hall. The rail station sits below the terminal complex. Use lifts when carrying a large case.
At the ticket area, choose the All-Stop Train toward Seoul and confirm that Gimpo Int’l Airport appears on the stopping pattern. The Express is the wrong service for this trip.
You can use a compatible stored-value transit card or the current ticket offered by AREX. VERIFY: Confirm the adult fare from T1 and T2, payment methods and T-money acceptance on the publication date.
From Terminal 1
Follow the Airport Railroad signs to the transportation center and B1 ticket area. Allow time from baggage claim to the platform. VERIFY: Record the step-free route, lift landmarks and walking time from two representative arrival exits.
From Terminal 2
Follow the rail signs to the Terminal 2 transportation center. T2 starts farther from Gimpo than T1 because the train calls at T1 after leaving T2. VERIFY: Record the platform route and actual time with one suitcase.
At Gimpo Airport Station
Leave at Gimpo Int’l Airport Station and follow signs for your correct flight terminal. The airport rail station connects with other metro lines and a large underground complex. Do not follow a generic “Airport” sign without checking domestic or international.
The Incheon Airport rail guide lists a T-Luggage point around the Line 5 gate toward Gimpo’s International Terminal, which helps identify the scale of the interchange but does not replace departure signs.
VERIFY: Walk from the AREX platform to domestic departures and international departures. Record lifts, indoor distance, accessible toilets and the point where airline signs become clear.
Airport bus
A direct bus can reduce station walking, but departure frequency and boarding bays matter. Check the live Incheon Airport bus search and the operating company. Ask the transport desk for Gimpo Airport, not Gimpo city.
VERIFY: Add current route number, T1 and T2 boarding bays, Gimpo drop-off order, fare, payment method, luggage allowance, first and last service.
Allow for traffic. A bus timetable cannot guarantee the arrival time. Rail remains the safer default when a road delay would threaten check-in.
Official taxi
Use the designated taxi stand. Incheon Airport publishes stand numbers, vehicle types and surcharge rules in its Taxi Guide, and warns against illegal solicitors.
Show the driver:
- “Gimpo Airport” and the Korean name
김포공항 - Domestic or international terminal
- Airline and flight number
- Departure time
VERIFY: Add a current metered range from each ICN terminal, expected toll treatment and traffic-sensitive time range. Do not present an estimate as a fixed fare.
A large taxi may suit a family whose passengers and suitcases cannot fit a standard car. Use the official queue or a traceable booking.
How much connection time should you allow?
Build the connection from separate parts:
- ICN arrival and deplaning
- Immigration, baggage and customs when required
- Walk to rail, wait and ride
- Walk through Gimpo station
- Airline check-in and bag drop
- Security and the gate walk
A traveler with carry-on luggage and both boarding passes has a different connection from a family entering Korea on separate tickets with checked bags. Weather, peak queues and reduced mobility add time.
Ask both airlines whether they recognize the connection and what happens after a delay. Travel insurance terms may distinguish a protected connection from self-transfer.
Luggage, children and accessibility
The All-Stop Train uses metro-style space. Keep bags clear of doors and aisles. Avoid blocking priority areas. At busy times, a family may find it easier to wait for a less crowded car only if the flight buffer remains strong.
Use lifts instead of dragging luggage on stairs or escalators. VERIFY: Confirm lift operation and any platform gaps along the tested route.
A traveler who needs airport assistance should arrange it with each airline in advance. Assistance at ICN does not transfer between unrelated airlines or airports without confirmation.
If your arriving flight is late
Check the next train and the onward airline cutoff before leaving baggage claim. A taxi cannot restore a missed check-in deadline. Contact the receiving airline while you still have staff and Wi-Fi access.
If the final AREX service has gone, compare the official bus with the taxi queue. If neither can deliver a credible margin, ask the airline about rebooking. Do not accept a ride from an arrivals-hall solicitor.
Plan B
Use the official taxi stand when rail stops or a lift outage makes the route inaccessible. Keep the current airport bus as a second public option only when traffic and schedule leave enough margin. If the connection is already broken, stop optimizing the route and work with the airline on a new flight before spending money on a rushed transfer.
