Pegasus Airlines, Turkey’s leading low-cost carrier, has announced a long-term maintenance partnership with CFM International to support its growing fleet of Boeing 737-10 aircraft. The airline has ordered up to 300 Leap-1B engines to power the new aircraft, with deliveries expected to commence in 2028. This expansion aims to reach a fleet size of approximately 100 Boeing 737-10s by 2033, complementing Pegasus’s current Airbus A320neo-family operations.
Güliz Öztürk, CEO of Pegasus Airlines, highlighted the longstanding relationship with CFM engines, stating, “Since our operations began in 1990, engine reliability has been crucial, and the Leap engine family has met our expectations. We look forward to applying this performance to our Boeing 737-10 fleet.”
Fleet Strategy and Industry Context
The carrier has historically shifted between aircraft manufacturers, initially operating Boeing 737NGs before transitioning to Airbus A320neo aircraft. Now, with the new Boeing 737-10s, Pegasus continues its reliance on CFM engines, despite some challenges faced by the Leap program.
“Despite some issues with the Leap engine, our overall fleet strategy remains focused on reliable, efficient aircraft,” stated Güliz Öztürk.
The article also discusses broader industry disruptions, noting that Pratt & Whitney geared turbofan issues have grounded about a sixth of Canadian airline Air Transat’s fleet, although prospects for improvement are positive. Air Transat’s CEO Annick Guérard predicts a significant reduction in groundings by 2026, with complete resolution anticipated soon thereafter.
