The maintenance delay rate, which indicates the proportion of flight delays caused by aircraft maintenance issues, is used as a key indicator to evaluate an airline’s safety and on-time operation capability. Jeju Air reduced its number of flights by approximately 14% in the first quarter of this year to enhance operational stability.

To strengthen operational stability, Jeju Air is also recruiting maintenance technicians in the operation, airframe, cabin maintenance, and maintenance management sectors. Additionally, overseas engine maintenance, repair, and overhaul (MRO) companies certified by the U.S. Federal Aviation Administration (FAA) and the European Union Aviation Safety Agency (EASA) performed medium-level maintenance on 18 engines in 2023 and 14 engines last year.
