Jeju Air is South Korea's first and largest low-cost carrier, founded in 2005 and headquartered in Jeju City, South Korea. The airline operates an extensive network of domestic and international routes across Asia, serving destinations in Japan, China, Southeast Asia, and beyond from its main base at Incheon International Airport. The carrier is known for offering affordable fares with an à la carte service model, allowing passengers to customize their travel experience. Jeju Air went public on the Korea Exchange in 2015, marking a significant milestone in its growth as a budget airline. In recent years, Jeju Air has expanded its fleet and route network aggressively, becoming one of the dominant low-cost carriers in Northeast Asia. The airline faced significant scrutiny following a tragic runway accident at Muan International Airport in December 2024.
