Its two modern, spacious terminals combine efficient service and spotless facilities with a wide array of dining options, duty‑free shopping, cultural experiences, and more. You’ll even find hotels, saunas, spa, and a golf course at the airport.

Designed with travelers in mind, the airport ensures smooth arrivals, quick departures, and comfortable layovers for any visitor.

Whether you are departing or transferring, passengers can easily move between the terminals and midfield concourse using the free inter-terminal shuttle train, which departs about every 5 minutes.

Additionally, free shuttle buses connect Terminal 1 and Terminal 2 from outside the secure area. Shuttle bus stops are located outside Exit 7 of Terminal 1 and between Exits 4 and 5 of Terminal 2. Buses run every 5-8 minutes and take about 20 minutes.

Passengers can also use the AREX train to travel between terminals. But, unlike the shuttle and bus, the AREX requires purchasing a ticket and is not free.

Travelers entering South Korea pass through immigration, collect checked baggage, and then clear customs. Entry requirements depend on your nationality and immigration status. Check the visas and passports guide and official requirements before departure.

K-ETA

Some travelers entering without a visa need a K-ETA. However, the temporary exemption for eligible countries and regions has been extended through December 31, 2026 (Korean Standard Time). Do not assume that every visa-free visitor needs to apply. Check your eligibility on the official K-ETA website before travel.

Travelers holding a valid K-ETA do not need to submit an arrival card. Travelers using the temporary K-ETA exemption generally still need an arrival card unless another exemption applies. See the official exemption extension notice.

Arrival Cards

If you need an arrival card, complete the free e-Arrival Card online starting three days before arrival in Korea, based on Korean Standard Time. Have your passport, flight details, and address in Korea ready.

Valid K-ETA holders, registered foreign residents, and certain other categories are exempt. Check the official immigration guidance for your circumstances.

Paper arrival cards are still recognized in the official guidance. Do not rely on your airline distributing them onboard. Completing the electronic form before you travel is the simpler option. If you have submitted an e-Arrival Card, you do not also need a paper card. See the official e-Arrival Card guide for current instructions.
