Pegasus Airlines (PC, Istanbul Sabiha Gökcen) has signed a firm order for 100 B737-10s from Boeing with a further 100 options, committing to a dual-manufacturer fleet starting in the late 2020s.

The Turkish low-cost carrier said that the deliveries of the first of the firm-ordered B737-10s are scheduled for 2028. It did not outline a further timeline.

The order marks Pegasus Airlines' return to a large Boeing fleet. The ch-aviation fleets history module shows it initially launched operations in 1990 with a fleet of B737-400s. It also operated three B737-500s between 2006 and 2012. It ordered its first B737-800 in 1997. With all B737 Classics retired by 2013, Pegasus' B737-800 fleet peaked at 53 units in 2016. However, it has since been gradually decreasing in favour of A320-200s and, more recently, A320-200Ns and A321-200NX.

The ch-aviation fleets module shows that the airline currently operates nine remaining B737-800s, six A320-200s, forty-six A320-200Ns, and fifty-seven A321-200NX. It also has 52 additional A321-200NX on order from Airbus. All of the remaining A321s are due to deliver by 2029.

While Pegasus Airlines previously planned to retire the B737-800s and focus on an all-Airbus fleet, the rapid capacity growth after the pandemic prompted it to extend their leases with no imminent retirement plans.

Separately, the airline has secured a sustainability-linked financing deal with CCB Financial Leasing, a wholly-owned subsidiary of China Construction Bank Corporation, for three A321-200NX, in line with its recently released Pegasus Guidelines for the Aviation Sector. The carrier says it is working to finance nine A321neo, which are part of its current aircraft order and due for delivery by the end of 2025.
