Jeju Air

What Jeju Air does

Jeju Air is South Korea's leading low-cost carrier, founded in 2005 and headquartered in Seoul with the airline's principal operational base at Incheon International Airport. The company operates scheduled domestic routes — most notably the high-volume Jeju-Gimpo corridor — alongside international services to Japan (including Kobe), Southeast Asia (Bangkok, Singapore, Vietnam), Indonesia, Central Asia, and Saipan. Its core product is passenger air transportation on a single, unified low-cost service, delivered using a Boeing 737 fleet that is being modernized with 40 new Boeing 737-8 aircraft ordered in 2022 to improve fuel efficiency, range, and route economics.

The business model is a direct-to-consumer, transaction-fee model: tickets are sold predominantly through Jeju Air's own website (jejuair.net) and airport counters, with ancillary revenue from optional paid services such as baggage, meals, and seat selection. Customer engagement is supported by digital channels including email, push notifications, and a J-points rewards program. Pricing is unit-based per ticket, with fuel surcharges layered on top and adjusted for oil price moves — international fuel surcharges recently rose to a $52-$126 range amid Middle East tensions and a weak Korean won.

Jeju Air is publicly listed (KRX: 089590) and operates with 1,001-5,000 employees. The company is in a defensive posture as of 2025: revenue has stepped down from a 2023 peak of roughly 1.33 trillion KRW to approximately 1.09 trillion KRW in 2025, the company reported an operating loss of 110.9 billion won, and it has cut 187 round-trip international flights while implementing unpaid leave. These pressures compound the reputational and regulatory fallout from the December 29, 2024 crash of Flight 2216 at Muan International Airport, which killed 179 of 181 people on board and triggered police, parliamentary, and audit investigations as well as a Boeing lawsuit.
