AREX Timetable: Incheon Airport to Seoul Train Times (Express & All-Stop)

AREX serves the Incheon Airport to Seoul route on two types of trains: a non-stop Express train and a more economical All-Stop train. Choosing the right option will depend on your destination and how fast you need to arrive in Seoul. In this article we will provide you with tips on the current timetable, fares and travel times.

⚠️Timetables can change, so check the operator's website before travelling. 

AREX Timetable at a Glance

This table gives you the key AREX times, fares and journey details in one place, making it easy to compare the two services before travelling.

Both services start at Terminal 2 (T2) and serve Terminal 1 (T1) before heading for Seoul Station. The Express makes no other stop. The All-Stop calls at 14 stations, including Gimpo Airport and Hongik University (Hongdae).

AREX Express Train Timetable (직통열차)

The Express is the faster of the two AREX services, running directly between the airport terminals and Seoul Station.

Incheon Airport → Seoul Station departures

These are the scheduled Express departures from both airport terminals, with the corresponding arrival time at Seoul Station.

The T1 time is when the train reaches your platform, not when the journey starts.

Seoul Station → Incheon Airport departures

The return service runs from Seoul Station to both airport terminals, with T1 reached before T2.

Trains from Seoul Station call at T1 first, then T2.

Weekday vs weekend and holiday timetable

The Express timetable does not change throughout the week, meaning you can rely on the same departure times no matter when you visit.

There is no difference. AREX has different tables for weekday and holiday schedules for the Express, but the number of trains and the timing remain the same, regardless of your travel date. The All-Stop timetable is the one that varies by date.

Which Express train should you catch for your flight?

Selecting your return train has a lot to do with working backwards from your airport arrival time. You need to take into account check-in, bag drop and travelling from the platform to the terminals.

Say, you have to be at T1 by 18:00. In that case, trains arriving at 18:08, such as the one departing from Seoul at 17:25, will probably leave you too late! The right time to leave here would be with the 16:50 train arriving at T1 at 17:33. Check train times carefully, as they run every half hour or so. A wrong departure could significantly delay your arrival. As for T2, add 8 more minutes!

Some airlines allow Express ticket holders to check in and drop off luggage at Seoul Station City Airport Terminal prior to flying. For departures from T2, check-in is closed 3 hours and 20 minutes prior to departure. Availability and hours of airlines vary, so be sure to confirm with your airline before travelling. 

AREX All-Stop Train Timetable (일반열차)

The All-Stop service offers more frequent departures and more stations, making it useful for several popular areas of Seoul and the surrounding region.

The All-Stop train works like a subway, making it a convenient choice if you're staying outside central Seoul. You can tap in with a transport card, and no reservation is needed.

• Seoul Station
• Gongdeok
• Hongik University
• Digital Media City
• Magongnaru
• Gimpo Airport
• Gyeyang
• Geomam
• Cheongna International City
• Yeongjong
• Unseo
• Airport Cargo Terminal
• Incheon Airport Terminal 1
• Incheon Airport Terminal 2

⚠️ If you're staying near Hongdae, Gongdeok or Gimpo Airport, you can get off directly at your destination instead of travelling to Seoul Station and doubling back.

Seoul Station and airport departures

In view of the fact that all-stop trains run very frequently, it is generally better to give just first and last timings rather than a complete list of departures.

Trains run every few minutes during the day, so first and last stops are more important than a complete list of trains. The operator writes the timings for times past midnight in 24:xx format.

⚠️ Be aware of the last trains running. Until about 11:50 PM, some services are terminated at the Digital Media City station instead of Seoul Station. The midnight train leaving from Seoul Station only arrives at Geomam. It is advisable to check the destination on the display in the station.

Weekday vs weekend differences

All-Stop services differ based on the day, meaning that you should look for the right timetable for your trip.

All-Stop schedules do change for Saturday and Sunday, unlike Express schedules, which remain unchanged for such days. While start-and-end trains are the same, individual departures will change by several minutes each day. Relying on the weekday table while travelling on a Sunday will lead to getting the wrong times, so make sure you use the right one at the station.

Station-by-station timetables

If you are boarding somewhere other than Seoul Station or the airport, AREX provides individual timetables for each station.

AREX publishes a separate timetable for each of its 14 stations, with weekday and holiday tabs. Use the one for your actual boarding station.

• Seoul Station
• Gongdeok
• Hongik University
• Digital Media City
• Magongnaru
• Gimpo Airport
• Gyeyang
• Geomam
• Cheongna International City
• Yeongjong
• Unseo
• Airport Cargo Terminal
• Incheon Airport Terminal 1
• Incheon Airport Terminal 2

Travel Times Between Key Stations

Journey times vary depending on the service and your boarding point, so these are the main routes most travellers are likely to need.

Express vs All-Stop: Which Should You Take?

The two AREX services suit different types of journeys, particularly when you are balancing travel time, cost and convenience.

Select the Express if you're going to Seoul Station or catching a KTX connection, travelling with hefty luggage or requiring a pre-booked seat. Select All-Stop if your lodging is in Hongdae, Gongdeok, Digital Media City, or Gimpo Airport, or you are on a budget.  

All-Stop prices are determined by distance travelled, but they are lower for younger passengers. For children between the ages of six and thirteen, the fare is ₩550 plus half of the full adult fare. The fare for children aged between 13 and 18 is ₩900 plus 80% of the same fare. Children under six are free of charge (though no more than 3 kids can do so while being under the guardianship of an adult).

Where to Check the Latest Official Timetable

AREX's official timetable is the best place to check for changes, particularly if you are travelling on a specific date.

AREX (Airport Railroad) is the operator, and its own pages are the only authoritative source. Third-party guides, this one included, can lag behind a revision.

First and Last Train: What If You Land Late?

Late arrivals require more planning than simply checking the final scheduled departure. You still need time to clear immigration, collect your bags and reach the platform.

Last Trains from Incheon Airport

The last Express leaves T2 at 22:40 and T1 at 22:48. The last All-Stop train reaching Seoul Station leaves T2 at 23:32 and T1 at 23:38. Later trains at 23:50 and 23:56 only run as far as Digital Media City.

If you're close to a cut-off, check the live train page once you've cleared arrivals.

After that, your options are night buses or taxis. Night buses run from the airport transport centre to central Seoul and Gangnam, but routes and times can change. Check the airport's current timetable before travelling. Taxis also have a night surcharge, which can make them much more expensive than daytime journeys.

First Trains for Early Flights

For early flights, the first Express from Seoul Station leaves at 06:00 and reaches T1 at 06:43. The first All-Stop leaves Seoul Station at 05:20 and takes about an hour.

If you need to check in earlier than either train allows, you'll need a taxi or another route.
