Incheon International Airport

Incheon International Airport (RKSI) sits 30 miles west of central Seoul on Yeongjong Island. Commercial service is overwhelmingly dominant — RKSI is the principal Korean Air and Asiana hub and the busiest international airport in South Korea — and the field handles a meaningful flow of business aviation alongside the airline operations. For Seoul-area close-in charter, Gimpo (RKSS, 9 miles west of central Seoul) is the dedicated alternative and is favored for domestic and short-stage charter movements.

The four runways at RKSI handle every current business jet without restriction. Two principal FBOs (Korean Air Business Jet Center and Asiana Airport Service) handle business movements. Slot pressure is meaningful during Korean Air banks. Field elevation is 23 feet, no density-altitude concerns. The dominant operational considerations are the Korean winter weather (cold, occasional heavy snow events), the East Asian monsoon (June–August) and typhoon (September–November) seasons, and the strict Korean aviation regulatory framework. Ground time to central Seoul via the AREX airport express train is 53 minutes (43 to Seoul Station); by car via the Incheon International Airport Expressway is 60–90 minutes depending on Seoul traffic; the Han River crossings add meaningful variability.

Incheon International Airport is the main international airport serving Seoul, the capital of South Korea. It is one of the largest and busiest airports in the world.
