Airport Railroad Express (AREX): Direct train service linking Incheon to Gimpo, fast and convenient travel option
The Airport Railroad Express (AREX) stands out as the most direct and efficient way to travel between Incheon International Airport and Gimpo International Airport. This dedicated train service eliminates the need for transfers, offering a seamless journey that connects two of Seoul's major airports in approximately 35 minutes. Unlike other options that may involve navigating traffic or multiple connections, AREX provides a straightforward solution for travelers looking to transition quickly between flights or continue their journey within the city.
For those prioritizing speed and convenience, AREX is the clear choice. The service operates at regular intervals, with trains departing every 10 to 15 minutes during peak hours. Passengers can board the train directly from Incheon Airport's Transportation Center (located between Terminal 1 and Terminal 2) and disembark at Gimpo International Airport Station, which is connected to the terminal via an underground walkway. The express train option, which costs slightly more than the all-stop service, reduces travel time by skipping intermediate stations, making it ideal for time-sensitive travelers.
One of the key advantages of AREX is its integration with Seoul’s broader public transportation network. Upon arriving at Gimpo Airport, passengers can easily transfer to the Seoul Metropolitan Subway system, including Line 5 and Line 9, or connect to domestic flights. The train’s spacious interiors, luggage racks, and clear signage in both Korean and English cater specifically to travelers, ensuring a stress-free experience even for first-time visitors. Additionally, tickets can be purchased at vending machines or through the AREX app, offering flexibility for tech-savvy travelers.
While AREX is a reliable option, it’s important to plan ahead during peak travel times, such as early mornings or late evenings, when trains may be busier. Purchasing tickets in advance or opting for a T-money card (Seoul’s rechargeable transportation card) can save time and streamline the boarding process. For those traveling in groups or with heavy luggage, the express train’s additional fee is a small price to pay for the convenience of a faster, more comfortable journey.
In summary, the Airport Railroad Express (AREX) is a traveler’s best ally for moving between Incheon and Gimpo Airports. Its combination of speed, convenience, and accessibility makes it an indispensable option for both domestic and international travelers. By choosing AREX, passengers can bypass the uncertainties of road travel and enjoy a smooth, efficient connection that sets the tone for a well-organized trip.

Bus Transfer Options: Multiple bus routes available, affordable and accessible for passengers with luggage
Traveling between Seoul’s Incheon International Airport (ICN) and Gimpo International Airport (GMP) by bus is a practical and budget-friendly option, especially for passengers with luggage. Multiple bus routes connect these two hubs, offering flexibility and convenience. The 6705B and 6002 buses are the most popular choices, with direct routes that eliminate the need for transfers. Both buses feature spacious interiors designed to accommodate travelers with suitcases, ensuring a comfortable journey. Fares typically range from 5,000 to 7,000 KRW (approximately $4–6 USD), making this one of the most affordable options available.
For those prioritizing affordability and accessibility, the 6705B bus stands out. Operating from 5:30 AM to 10:30 PM, it runs every 20–30 minutes, providing ample departure times. The journey takes approximately 40–60 minutes, depending on traffic. Passengers can board at Incheon Airport’s bus terminal (located outside Exit 4 of Terminal 1 or Exit 11 of Terminal 2) and disembark directly at Gimpo Airport’s international terminal. Luggage storage racks are available onboard, though arriving early ensures a spot for larger bags. Payment can be made in cash or with a T-money card, adding to its convenience.
Alternatively, the 6002 bus offers a slightly faster route, taking around 35–50 minutes under normal conditions. It operates from 5:00 AM to 11:00 PM, with departures every 15–20 minutes. This bus is ideal for travelers arriving late or departing early, as its extended hours cater to a wider range of flight schedules. The route includes stops at both Incheon and Gimpo Airports, with clear signage in English and Korean to guide passengers. While the 6002 is slightly more expensive than the 6705B, its frequency and speed make it a compelling choice for time-conscious travelers.
A key advantage of bus transfers is their accessibility for passengers with luggage. Both the 6705B and 6002 buses are equipped with low floors and wide doors, making it easy to board with heavy bags. Additionally, drivers are often willing to assist with luggage placement, though tipping is not customary in South Korea. For added convenience, consider using a luggage tag or app to track your bags, especially during peak travel times. While buses may experience delays due to traffic, real-time updates are available via airport information boards or navigation apps like Naver Map.
In conclusion, bus transfers between Incheon and Gimpo Airports offer a winning combination of affordability, accessibility, and convenience. Whether you choose the 6705B for its cost-effectiveness or the 6002 for its speed, both routes cater well to travelers with luggage. By planning ahead—checking schedules, arriving early, and using a T-money card—passengers can enjoy a stress-free journey between Seoul’s major airports. For those seeking a balance of price and practicality, buses remain an unbeatable option in this bustling metropolis.

Taxi Services: Direct taxi rides, quickest but pricier, ideal for groups or late arrivals
For travelers seeking the most direct and time-efficient transfer from Seoul Incheon Airport to Gimpo Airport, taxi services emerge as the premier option. This choice is particularly advantageous for groups or individuals arriving during late hours when other transportation methods may be less frequent or convenient. A typical taxi ride between these two airports takes approximately 30 to 45 minutes, depending on traffic conditions, making it significantly faster than public transit alternatives like the AREX train or buses, which can take upwards of an hour with transfers.
When opting for a taxi, passengers have two primary choices: standard metered taxis or pre-booked airport taxi services. Standard taxis are readily available at Incheon Airport’s taxi stands and operate on a metered fare system, with the cost ranging from 30,000 to 40,000 KRW (approximately 25 to 35 USD) for the trip. While this option is straightforward, it’s essential to ensure the driver understands your destination, as language barriers can occasionally arise. Pre-booked airport taxis, on the other hand, offer fixed rates and the convenience of a reserved vehicle waiting upon arrival. These services often include English-speaking drivers and can be arranged online or through hotel concierge desks, providing peace of mind for international travelers.
For groups of three or more, the cost-effectiveness of a taxi becomes more apparent. Splitting the fare among passengers can make it comparable to or even cheaper than individual train or bus tickets, while offering the added benefits of door-to-door service and luggage convenience. Additionally, taxis are ideal for late arrivals or early departures, as public transportation options like the AREX train cease operation between midnight and 5:30 AM. During these hours, taxis remain the most reliable and accessible choice, ensuring travelers can reach Gimpo Airport without delay.
Practical tips for a smooth taxi experience include having the destination written in Korean (e.g., “김포공항” for Gimpo Airport) to show the driver, confirming the fare type (metered or fixed) before departure, and carrying cash, as some taxis may not accept credit cards. For those prioritizing speed, comfort, and flexibility, taxis undeniably stand out as the optimal solution for navigating between Seoul’s two major airports.

Subway Connections: Use Seoul Metro lines with transfers, cost-effective but requires navigation skills
Navigating Seoul’s intricate subway system to travel from Incheon Airport to Gimpo Airport is a cost-effective option, but it demands a blend of confidence and preparation. The journey involves transferring between the AREX (Airport Railroad Express) and Seoul Metro lines, with a total travel time of approximately 60–75 minutes, depending on transfer efficiency. Fares range from 4,000 to 5,000 KRW per person, significantly lower than taxi or shuttle bus alternatives. However, this method is best suited for travelers comfortable with reading maps, managing luggage on escalators, and handling potential language barriers at ticket machines.
The journey begins at Incheon Airport Station (Terminal 1), where you’ll board the AREX train toward Seoul Station. Opt for the General Train (not the Express) to save costs, as it stops at Gimpo Airport Station, your transfer point. The AREX ride takes about 35 minutes. At Gimpo Airport Station, follow signs to the Seoul Metro Line 9 or Line 5, depending on your preference. Line 9 offers a direct connection to Gimpo International Airport Station, while Line 5 requires an additional transfer at Gimpo Airport Intersection. Both routes are viable, but Line 9 is more straightforward for first-time users.
Transferring between lines is where navigation skills are tested. Seoul’s subway stations are well-signed in both Korean and English, but the sheer size of hubs like Gimpo Airport Station can be overwhelming. Use the official Seoul Metro app or Naver Map for real-time guidance, and ensure your T-money card (rechargeable transit card) is topped up to avoid delays at ticket machines. Luggage storage areas are available at key stations, but dragging bags through crowded platforms during peak hours (7–9 AM and 6–8 PM) can be challenging.
Despite its complexities, the subway route offers a unique glimpse into Seoul’s daily rhythm. The cost savings and the satisfaction of mastering the system make it a rewarding choice for budget-conscious travelers. However, those with heavy luggage, mobility issues, or tight schedules may find this option less practical. For a seamless experience, arrive at Incheon Airport Station early, familiarize yourself with station layouts beforehand, and carry a portable charger—your phone will be your most valuable tool during this journey.

Shuttle Services: Airport-operated shuttles, scheduled departures, comfortable and reliable for seamless transfers
For travelers seeking a hassle-free transfer between Seoul Incheon Airport (ICN) and Gimpo Airport (GMP), airport-operated shuttle services emerge as a standout option. These shuttles are designed with efficiency in mind, offering scheduled departures that align with flight times, ensuring passengers can seamlessly transition between airports without unnecessary delays. Operated directly by the airports, these services prioritize reliability, making them a trusted choice for both domestic and international travelers.
The journey between Incheon and Gimpo airports spans approximately 40 kilometers, and shuttle services typically complete this route in 50 to 70 minutes, depending on traffic conditions. Shuttles depart at regular intervals, often every 10 to 20 minutes during peak hours, and less frequently during off-peak times. This scheduling flexibility ensures that passengers can plan their transfers with confidence, knowing there’s always a shuttle ready to accommodate their needs. For added convenience, shuttle stops are strategically located near key terminals, minimizing walking distances and simplifying the boarding process.
Comfort is another hallmark of these shuttle services. Vehicles are equipped with spacious seating, ample luggage storage, and modern amenities such as air conditioning and Wi-Fi, ensuring a pleasant journey. This is particularly beneficial for travelers with long layovers or those carrying heavy baggage, as the shuttles are designed to cater to a wide range of passenger needs. Additionally, the drivers are trained professionals, prioritizing safety and punctuality, further enhancing the overall travel experience.
One practical tip for using these shuttle services is to check the schedule in advance, either online or at the airport’s information desk, to align your departure time with your flight schedule. Tickets can typically be purchased on-site at designated counters or kiosks, with fares ranging from 8,000 to 10,000 KRW (approximately $6 to $8 USD) per person. For frequent travelers, consider downloading the official airport app, which often provides real-time updates on shuttle departures and arrivals, ensuring you stay informed and on track.
In comparison to other transfer options like taxis or public buses, airport-operated shuttles strike a balance between affordability and convenience. While taxis offer door-to-door service, they can be significantly more expensive, especially during peak traffic hours. Public buses, on the other hand, are cheaper but require more navigation and may involve transfers, making them less ideal for those unfamiliar with the area. Shuttles, therefore, stand out as the most streamlined option, combining cost-effectiveness with the reliability and comfort needed for a stress-free transfer between Seoul’s two major airports.
