Jeju Air fleet

Jeju Air operates a single-aircraft fleet type: the Boeing 737, a proven narrow-body jet perfectly suited to the airline's route network across Asia. The 737's efficiency, reliability, and commonality streamline crew training, maintenance, spare-parts inventory, and operational costs-key advantages for a low-cost carrier.

The aircraft's two-class seating layout accommodates both economy and premium-economy passengers, allowing the airline to offer flexible fare options. With a typical range of 2,500–3,000 nautical miles (depending on variant), the 737 covers all of Jeju Air's primary domestic and regional routes without compromise, from Seoul to Jeju, to Japan, China, and Southeast Asian destinations.
