Quick Answer
For most travelers, the best way to get from Gimpo Airport (GMP) to Incheon Airport (ICN) is via the Airport Railroad (AREX) train with one transfer at Seoul Station. The journey takes 60-75 minutes and costs about 9,000 KRW ($6.80 USD). The cheapest option is a public bus (from 5,000 KRW / $3.80), while a taxi is the fastest door-to-door option (45-60 mins) but costs 65,000-80,000 KRW ($50-$62).
By Train: The Airport Railroad (AREX) – Best Balance of Speed & Cost
The Airport Railroad (AREX) is South Korea's dedicated airport train line, connecting Gimpo and Incheon Airports via Seoul. It's the most recommended option for its punctuality, frequency, and value.

Deep Dive: AREX All-stop vs. Express
- All-stop Train: The practical choice. Runs every 6-12 minutes. No seat reservation needed (first-come, first-served). Has luggage racks and standing room. Perfect for budget travelers and those with standard luggage.
- Express Train: Slightly faster and guarantees a seat. Must purchase a specific timed ticket. Ideal for travelers with heavy luggage who value guaranteed seating and want to minimize standing time. Not cost-effective for this short leg.
Pro Tip: Purchase and top up a T-money card at the station. It works for the entire journey (with transfer discount) and on all Seoul public transport.
By Bus: The Most Economical Option
Public and airport limousine buses offer the lowest cash fare and deliver you directly to major hubs in Incheon City and Incheon Airport. They are ideal for ultra-budget travelers and those with lodging near a bus stop.

- Payment: Cash (exact change recommended) or T-money card. Inform the driver if you need a transfer receipt.
- Luggage: Buses have undercarriage luggage compartments. There's typically no extra fee for standard suitcases.
- Reliability: Travel time is an estimate. The route uses expressways that are prone to congestion, especially during weekday rush hours and holidays. Always add a 30-60 minute buffer if you have a flight to catch at ICN.
Verdict: Choose the bus if cost is your absolute primary concern and you have ample time. For time-sensitive airport transfers, the train is vastly more reliable.
By Taxi & Private Transfer: Door-to-Door Convenience
Taxis and private transfers offer the ultimate in convenience, taking you directly from Gimpo Airport arrivals to your specific address in Incheon or Incheon Airport. This comes at a significant premium.

- Deluxe / Mobi Taxi (Black): More expensive, larger vehicles. Fares can be 50-100% higher than standard taxis.
- Private Van Transfer (Pre-booked): Ideal for groups of 4-9 or those with excessive luggage. Prices start around 120,000 KRW ($90) for a sedan and go up for vans. Book via services like Klook or Viator.
When is a Taxi the Right Choice?
Consider a taxi or private transfer only in these specific scenarios:
- Late-Night/Early-Morning Arrivals: When public transport has stopped.
- Traveling in a Group (3-4 people): The per-person cost can become competitive with train tickets.
- Those with Mobility Issues or Excessive Luggage: Direct curb-to-curb service.
- Extremely Tight Connection: If you have less than 2 hours between landing at GMP and needing to check-in at ICN (a stressful situation).
Warning: Always ensure the taxi uses the meter or agree on a fixed price beforehand. Avoid unsolicited drivers inside the terminal.

Traveler Experience & Essential Tips
Navigating the Transfer at Seoul Station
This is the only complex part of the train journey. Don't panic. Upon arriving at Seoul Station from Gimpo, follow the clear blue signs for "Incheon International Airport Railroad". You will need to tap out of one fare gate and immediately tap into another for the AREX line. The cross-platform transfer takes 3-5 minutes. Allow 10 minutes if you're unsure.
Luggage Strategy
- Light Packers: The train is easy. Use overhead racks or hold your bag.
- Heavy Luggage (Large Suitcases): On All-stop trains, use the multi-purpose areas at the ends of each car. Avoid rush hour (7-9 AM, 6-8 PM) when trains are crowded.
- Consider Baggage Delivery (Takkyubin): If you have multiple heavy bags and are going straight to Incheon Airport to fly out, consider using Korea's excellent luggage forwarding service (e.g., CJ Logistics). You can send bags from Gimpo Airport directly to your departure terminal at ICN, then travel with just a daypack. Cost: ~15,000-25,000 KRW per bag.
Critical Time Considerations
- Rush Hour: Seoul's metro and roads are packed on weekday mornings and evenings. This affects bus travel times significantly and can make trains standing-room only.
- Holiday Periods: During Lunar New Year (Seollal) and Chuseok (Korean Thanksgiving), all transport is exceptionally busy. Book private transfers weeks in advance or stick to trains, which are less affected by road traffic.
- Flight Check-in Buffer: If going to Incheon Airport for an international flight, you must be checked in at least 2-3 hours before departure. Factor this into your total travel time from Gimpo.
Final Pro Tip: Download the app "Subway Korea" or "KakaoMap" (website). They provide real-time transit navigation, station maps, and accurate bus/train schedules in English.
FAQs: Gimpo Airport to Incheon Transit
Is there a direct train from Gimpo Airport to Incheon Airport?
No, there is no single direct train. The most efficient route requires one transfer. You take the Airport Railroad (AREX) from Gimpo Airport to Seoul Station, then transfer to the AREX Express or All-stop train directly to Incheon Airport Terminal 1 or 2. Total travel time is approximately 60-75 minutes.
What is the cheapest way to get from GMP to Incheon?
The cheapest option is the public bus (e.g., Bus 6011, 6009). Fares start from around 5,000 KRW ($3.80 USD). While economical, travel time can be 90-120 minutes depending on traffic. The AREX All-stop train is also budget-friendly at about 4,750 KRW ($3.60) but requires a transfer.
How long does a taxi take from Gimpo to Incheon Airport?
A taxi or private car takes about 45-60 minutes under normal traffic conditions. However, during rush hour (7-9 AM, 6-8 PM), this can extend to 90+ minutes. The fixed fare for an international taxi is approximately 65,000-80,000 KRW ($50-$62).
I arrive at Gimpo late at night (after 11 PM). What are my options?
Late-night options are limited. The last AREX train departs around midnight. Your best bets are: 1) Taxi (available 24/7, but most expensive), 2) Pre-booked private transfer, or 3) Staying at a transit hotel near Gimpo and traveling to Incheon the next morning. Night buses are not a common option for this route.
Which is faster: train or bus?
The train (AREX) is generally faster and more reliable than the bus. The train journey (including transfer) takes 60-75 minutes and is unaffected by road traffic. The bus can take 90-120 minutes and is highly susceptible to congestion, especially on the Incheon International Airport Expressway.
Is the AREX train covered by the Korea Tour Card or T-money?
Yes. You can use a T-money card, Cashbee card, or Korea Tour Card to tap on and off both the AREX and Seoul Metro for transfers. This is more convenient than buying single-journey tickets and offers a small fare discount (about 100 KRW per trip). Cards can be purchased and topped up at station vending machines.
I have a long layover (6+ hours). Can I visit Incheon city?
A 6-hour layover is tight but possible for a quick visit to areas like Incheon's Chinatown or Songdo Central Park. Take the AREX to Incheon Station (~55 mins). Allow 2 hours for immigration/security re-entry at Incheon Airport. It's stressful and not recommended unless your layover is 8+ hours.
Where do I catch the bus to Incheon at Gimpo Airport?
Buses to Incheon and Incheon Airport depart from the Gimpo Airport International Terminal (1F). Exit the arrivals hall and look for the clearly marked public bus stops. Signs are in English and Korean. Key buses are 6011 (to Incheon Airport) and 6009 (to Incheon Station area). Pay with cash or transportation card.
