Incheon International Airport

The A'REX train link connects the airport to Seoul Station (for further connections to KTX high-speed services) and Gimpo Airport (most domestic flights), operating from 05:20 until 00:00. There are express services and all-stop services.

Express services to the city (every 40 minutes) takes 43 minutes (Terminal 1 to Seoul Station) or 51 minutes (Terminal 2 to Seoul Station) and cost ₩9,000/₩7,000 (adult/child) (with WiFi available on board). There is a discounted fare of ₩7,500 for travelers taking a roundtrip within 15 days, groups of three and passengers of certain airlines (see here for more details and discounts).

All-stop services (every 6 minutes as part of the Seoul Subway system) take an hour and cost ₩4,150 from T1/₩4,750 from T2. It is often faster to just take the All-Stop than wait for the Express train.

The All-Stop and the Express train leave from different platforms and have separate ticket booths.

Travelers coming from Seoul Station to Incheon need to enter the subway area with a T-money or single entry ticket to access the AREX platforms. The cost of the subway ticket is refunded when buying an AREX ticket. The All-Stop train requires a T-money card or single entry ticket, which require cash. The Express train can be paid with credit card as well.

If you are flying with Korean Air, Asiana Airlines, T'Way Air and Jeju Air you can check into your flight at Seoul Station before you get on the AREX Express train if you are there at least 3 hours before your departure time. Immigration officers are also on hand to stamp your passport, which means you are processed and can quickly go through the Diplomatic Departures entrance in Incheon Airport. See City Airport Terminal.

Travel time to Gimpo Airport is 28/35 minutes, with both services charging ₩3,100, making this the fastest and cheapest option for inter-airport transfer as well.

In February 2016, Incheon opened a new maglev line to the area around the airport. It runs between the airport's Terminal 1 station and Yongyu Station in Youngyu Island, stopping at the airport administration building, long-term parking lots, and a couple of other places along the way. With a maximum speed of 110 km/h (68 mph), it is not exactly in the same class as the Shanghai Maglev, but may still be interesting to tourists wishing to ride a maglev for the first time or those in town for an event on Yongyu. The train runs every 15 minutes from 09:00 and 18:00, and fares are free for the first few years after opening.

Korea's high speed rail service (KTX) running directly to and from Incheon Airport have been suspended. To use the KTX, take the AREX to Seoul Station or Bus No. 6770 (₩15,000) to Gwangmyeong Station. Bus 6770 is operated by Korail, and there is a ₩3000 discount for the combined ticket for KTX and the bus. City Airport Terminal at Gwangmyeong Station can be faster than going to Seoul station.

When traveling into Seoul with a lot of luggage or heading to southern parts of Seoul (e.g. Gangnam) then the airport buses are a very good option. Limousine buses (₩15,000 to/from city for one way, ₩6,500 to/from Gimpo Airport (domestic flight)) travel directly to major areas and big hotels in Seoul, while public buses (₩8,000-9.000) will take you to major transit hubs. If you're visiting for the first time, it's worth paying a bit extra for the limousine bus. For either bus type, consult the big maps or staff to figure out which route best suits your needs; you can then find the shuttles outside 1st floor arrivals (if possible get this information from your hotel before arriving). Or simply, walk out and ask the many ticket sellers (they are wearing vests) which bus goes to your hotel because if it's a popular one or in a popular area, they'll surely know which you'll need. It's best to buy tickets at any of the ticket gates near the bus arrival area but you can also pay the fare using won or a T-Money card if you have one. The limousine bus drivers are extremely friendly but don't count on them knowing too much English. There are maps inside the buses letting passengers know which stops are upcoming and these are also announced in Korean and English. Pressing any of the red buttons inside signals to the driver you want off at the next stop.

You can purchase and recharge a T-Money card at the GS25 store which is located at the end of the arrivals area, next to "International Arrivals F" exit.

If you have a late flight and plan on getting into Seoul via bus, make sure you get out to the curb as soon as you can. The last buses run shortly after the last flights land. If you miss your bus, you'll be stuck paying for a taxi, as the trains will stop running too.

There are also inter-city and express bus to cities other than Seoul.

A taxi direct to Seoul will cost around ₩50,000/70,000 regular/deluxe. Black deluxe taxis (모범 택시) and almost all regular taxis accept credit cards, but a few regular taxis (일반 택시) may not. Ask the driver before you get on if you can pay by credit card. You are expected to pay any road tolls on top of the meter fare. Having your destination written down in Korean will be very helpful. Steer clear of taxi drivers trying to pick you up from inside the terminal and even the bus stop. As both buses and taxis are subject to traffic, allow extra time for rush hour delays (or take the train back).

It is connected by two highways. Incheon International Airport Expressway (No. 130) is connected to Seoul and north of Incheon. Incheon Bridge (No. 110, the longest bridge in South Korea) is for the people heading to the south of Incheon or other parts of region.

At the City Airport Terminal, you can check your bags and even pass through security and immigration, allowing you to skip the lines at the airport and to spend a little longer in the city, or helping you make a mad dash to the airport. It is located at COEX, Seoul Station, and Gwangmyeong Station. Not all airlines operate at City Airport Terminals. Make sure to check.
