About ICN

South Korea's main international gateway, built on reclaimed land between two islands west of Seoul. It is the hub of Korean Air and Asiana and one of the world's top-ten airports for international traffic and cargo. The airport is renowned for fast transfers, cultural experiences and an on-site skating rink and golf course.

Incheon International Airport was born of Gimpo Airport's saturation and Seoul's ambition to build a world-class hub. Beginning in 1992, engineers walled off the tidal mudflats between Yeongjong and Yongyu islands in the Yellow Sea, joined the two islands with seawalls.

Filled the space between to create an entirely new airport site. Incheon opened in March 2001, taking over virtually all of Seoul's international traffic. Quickly earned a reputation for efficiency and service that saw it win Airports Council International's service quality award year after year.

Terminal 2 opened in January 2018, just ahead of the PyeongChang Winter Olympics, giving Korean Air and its SkyTeam partners a dedicated home while Asiana and Star Alliance carriers remained in Terminal 1. The fourth phase of construction, completed in 2024, expanded Terminal 2 dramatically and added a fourth runway, lifting annual capacity beyond 100 million passengers and placing Incheon among the largest airports on the planet.

Throughout its growth the airport has doubled as a showcase for Korea, with cultural museums, gardens and entertainment woven into its terminals. It consistently ranks among the world's leading cargo airports.

How ICN operates today

Incheon operates four parallel runways flanking two large terminals and a satellite concourse, all connected by underground people movers. Terminal 2 belongs to Korean Air and SkyTeam, Terminal 1 to Asiana, Star Alliance carriers and low-cost airlines.

Transfer flows between them are finely tuned for the airport's role as Northeast Asia's premier connecting hub. The cargo terminals rank among the busiest in the world for international freight, moving semiconductors and electronics around the clock. The Airport Railroad Express links both terminals to Seoul Station, and an airport city with hotels, a casino and logistics parks surrounds the field.
