Fares reported by third-party guides range from about 4,150 to 5,350 KRW, so check the current price at the ticket machine before you pay. The ride takes roughly 56 to 66 minutes.

Quick facts

A note on the prices in this guide

The official Incheon Airport transport pages could not be retrieved when this guide was prepared, so every price and time below comes from third-party travel guides. These sources do not always agree with each other. No 2026 fare announcement was confirmed. Before you quote or budget for any fare, check the current price at the station machines or on the official AREX or Korail website.

The cheapest option: AREX All-Stop train

The AREX All-Stop train is the budget choice for most travelers. It starts at B1 in both Terminal 1 and Terminal 2 and ends at Seoul Station.

Sources disagree on the fare. The figures run from about 4,150 to 5,350 KRW. Terminal 2 costs a bit more than Terminal 1, and one source lists 4,150 KRW from Terminal 1 and 4,750 KRW from Terminal 2. Treat these as rough guides only.

The ride takes roughly 56 to 66 minutes. Along the way the train stops at Digital Media City (디지털미디어시티), Hongik University (홍익대학교), better known as Hongdae (홍대), and Gimpo Airport (김포공항). If your hotel is near Hongdae, you can get off there and skip the trip to Seoul Station.

How often trains run depends on the source. Reports range from every 6 to 12 minutes up to every 23 minutes. Plan for some waiting, especially late in the evening. One source says the train runs until about midnight, but this is unconfirmed, so check the timetable if you land late.

At Seoul Station you can transfer to Seoul Subway Lines 1 and 4, which makes it easy to reach most parts of the city.

The faster option: AREX Express

The AREX Express is a non-stop train to Seoul Station. It takes about 43 minutes from Terminal 1 and about 51 minutes from Terminal 2, and it runs about every 30 minutes.

Reported fares are 9,500 KRW, or 11,000 to 11,500 KRW for an in-person ticket that includes a 500 KRW refundable deposit. These are third-party figures, so verify them. Another source reports the last Express departures at around 22:10 from Terminal 1 and 21:50 from Terminal 2. This is also unconfirmed. If you arrive late, the All-Stop train, a bus or a taxi may be your only choices.

The Express costs more than the All-Stop but saves a fair amount of time. It makes sense if you are tired, carrying heavy bags, or heading straight to Seoul Station.

Airport buses

Limousine buses cost roughly 10,000 to 18,000 KRW depending on the route. They take 60 to 90 minutes depending on traffic. They are worth considering if a bus stops close to your hotel, because you avoid carrying luggage through subway stations.

There are also regular city buses, about 30 routes in total, priced by distance. One source gives 17,000 KRW for the 6011 to Gyeongbokgung Palace (경복궁). Bus fares can be paid with T-money.

Taxis

A taxi costs roughly 55,000 to 80,000 KRW plus 3,000 to 5,000 KRW in tolls. From midnight to 4 a.m. there is a 20% surcharge. A taxi is the most expensive option, but it can be the most practical for a group splitting the fare or for a very late arrival.

Get a T-money card first

T-money is the rechargeable transit card used across Korea. You can use it for trains, subways and buses. A few tips from third-party guides:

  • Buy a T-money card at convenience stores in Terminal 2, or at the machines on B1 in either terminal.
  • The machines next to the turnstiles sell a pricier "Korea Tour" version with tourist discounts. Compare it with the standard card before you buy.
  • Reload machines accept cash only, so carry some won.

How to get there: step by step

  1. After you clear immigration and collect your bags, follow the signs for the AREX train to B1. This applies to both Terminal 1 and Terminal 2.
  2. Buy a T-money card at a B1 machine or a convenience store. If you buy from a machine, remember that the ones next to the turnstiles sell the pricier Korea Tour version.
  3. Load some cash onto the card. Reload machines take cash only.
  4. Choose your train. Take the All-Stop for the lowest fare, or the Express if you want a non-stop ride.
  5. Check the current fare at the machine or on the official AREX or Korail site, since third-party prices vary.
  6. Ride to Seoul Station, or get off earlier at Digital Media City, Hongdae or Gimpo Airport if one of them is closer to your hotel.
  7. At Seoul Station, transfer to Subway Line 1 or Line 4 if your hotel is elsewhere.

Which option should you choose?

  • Lowest cost: AREX All-Stop train.
  • Fastest to Seoul Station: AREX Express.
  • Less walking with luggage: a limousine bus, if a stop is near your hotel.
  • Very late arrival or a group: a taxi, keeping the midnight surcharge in mind.

Use the right map app

Google Maps gives poor directions in Korea. For transit routes, use Naver Map or KakaoMap instead. Download one before you leave home and check your hotel's location on it.

Final tip

For the cheapest trip, board the AREX All-Stop at B1, carry a T-money card with some cash on it, and confirm the fare at the station. SIM and eSIM options, money exchange and the tax refund process are also worth sorting out on your first day, so check the official sources for each before you travel.

Korea eSIM vs SIM Card for Tourists: 2026 Guide

For most short trips, a Korea eSIM is the easier choice for tourists. It is bought online, installed before you fly, and gives you data only. A physical SIM is better if you need a Korean 010 phone number or your phone is too old for eSIM. This guide is part of a Korea first-day series and covers the connectivity step. Prices below are indicative and unconfirmed for 2026, so check the seller's site before you buy. Best for a short, data-only trip: an eSIM on a compatible, carrier-unlocked phone. Best if you need a Korean number: a physical tourist SIM, usually with a 010 number. Indicative price: third-party eSIM roughly ₩3,000–3,500 per day (unconfirmed). Pickup hours: vary by airport and desk, from 06:00–22:00 to 24 hours (see the list below). Location: eSIM is bought online. Physical SIMs are collected at airport desks, such as Incheon International Airport (인천국제공항). Nearest station: not applicable for an eSIM. For desks, check the airport's own transfer infor...
