Incheon International Airport

Incheon International is South Korea's primary international gateway and one of the most decorated airports globally — ASQ rankings by ACI have placed ICN at or near the top for more than a decade, a run unmatched by any peer. It serves 109 airlines on 499 routes reaching 175 nonstop destinations and handles roughly 80% of South Korea's international passengers and an outsized share of its international air cargo, which ranks among the top five globally by tonnage. The airport sits on reclaimed land between Yeongjong and Yongyu islands in the Yellow Sea, 48 km (30 mi) west of central Seoul. Korean Air operates its global hub here, with Asiana Airlines running the second-largest base and the two now in the process of merger integration. ICN has been purpose-built from the start as a sixth-freedom connecting hub, capitalizing on South Korea's geographic position between North America, China, Southeast Asia, and the rest of Northeast Asia — Seoul is among the shortest-great-circle connection points between several major trans-pacific origin and destination pairs. Four parallel runways, all 12,303 ft (3,750 m) or longer, allow triple-independent operations, with a fifth runway under construction as part of Phase 4 expansion. Two terminals — T1 (SkyTeam and most non-alliance) and T2 (Korean Air and partners) — are joined by a landside transportation center and by an airside shuttle-train system serving the Terminal 1 concourse building (Satellite). The 2018 opening of T2 delivered one of the largest passenger terminals built in the last decade. ICN is the flagship for integrated landside commerce: golf course, casino, ice skating, museum, and a six-story hotel complex are all embedded in or adjacent to the terminal envelope.
