The current international terminal, completed in 1988, has firmly established itself as the representative international airport of South Korea.

As the only international airport in the country connected to the capital, Seoul, by subway, the terminal must solidify its identity as Seoul’s business airport to ensure sustainable development and enhance its competitiveness. With this in mind, the airport was designed as a dignified and sophisticated sustainable transportation space, aligning with the concept of being Seoul’s representative business airport. This involved the development of a concept slogan and interior design that reflect its prestige and elegance.
