A fresh mega‑order from Turkey’s Pegasus Airlines has pushed CFM International’s LEAP engine programme to a new milestone, reinforcing the dominance of the French‑linked manufacturer in the global narrow‑body segment.
Pegasus signs record engine deal to match its Boeing splurge
Pegasus Airlines has finalised a major agreement with CFM International for 300 LEAP‑1B engines, the powerplant dedicated to the Boeing 737 MAX family.
The contract mirrors the carrier’s headline‑grabbing aircraft order from late 2024, when it committed to 100 Boeing 737‑10s, the largest variant of the MAX line.
The engine deal, including spares and long‑term maintenance, is valued by industry analysts at between €3 billion and €5 billion over its lifetime.
Both sides declined to reveal precise financial terms. Still, the scale is clear: the order covers engines for the incoming aircraft, backup units, and a long‑horizon service package designed to keep planes flying almost around the clock.
For a low‑cost airline like Pegasus, that last point matters as much as the sticker price. Its business model rests on rapid turnarounds and high aircraft utilisation, where every unscheduled hour on the ground eats into margins.
A long‑standing partnership between Pegasus and CFM
Pegasus is far from a newcomer to CFM technology. The Turkish carrier has essentially grown up with the Franco‑American engine maker.
It first operated the CFM56‑3 on earlier 737s, then shifted to the CFM56‑5B and CFM56‑7B as it modernised the fleet. When the LEAP family emerged, Pegasus moved quickly.
In 2016, it became the first airline in the world to use LEAP engines on a commercial flight, operating a service between Istanbul and Antalya. That early adoption gave Pegasus a head start in fuel efficiency and maintenance data compared with some rivals.

Today, the LEAP‑1B sits at the heart of Pegasus’s next growth phase, knitting together fleet expansion, cost control, and decarbonisation goals.
Leap‑1b: a workhorse built for low‑cost intensity
While the LEAP‑1B descends from the legendary CFM56 line, it is more than a facelift.
The engine uses composite fan blades to cut weight, ceramic matrix composites in the hottest sections to handle extreme temperatures, and advanced health‑monitoring systems that track wear and predict faults before they lead to disruption.
These technologies deliver roughly 15% lower fuel burn and a similar cut in CO₂ emissions versus earlier CFM56 engines, according to CFM data.
For Pegasus, that translates into lower fuel bills on every sector and a smoother path to complying with tightening European emissions policies.
The LEAP‑1B also suits the punishing rhythm of a low‑cost schedule. It is designed for short ground times, frequent cycles, and near‑continuous use during peak seasons. That resilience supports the airline’s push to keep aircraft in the air for as many hours a day as feasible.
The 737‑10 as a capacity lever
The 737‑10, the largest member of the MAX family, can seat up to about 230 passengers in a high‑density layout. Pegasus will use it to carry more travellers per flight on busy regional and medium‑haul routes.
That extra capacity means the airline can sell more seats without proportionally increasing crew, airport, and navigation charges, lowering cost per seat. The LEAP‑1B’s efficiency tempers the fuel hit that usually comes with a larger airframe.
- Bigger aircraft, more seats per flight
- Lower fuel burn per seat thanks to LEAP‑1B
- Reduced unit costs, helpful in tight‑margin markets
In an environment where Turkish and European carriers compete fiercely on fares, every fraction of a cent saved per available seat‑kilometre can decide who wins a route.
A young fleet as a strategic asset
Pegasus currently operates one of the youngest fleets in global aviation, with an average age of around 4.9 years. That youth brings several structural benefits.
Newer aircraft typically consume less fuel, face fewer technical issues, and integrate more easily with current noise and emissions standards.
By doubling down on the latest 737‑10s and LEAP‑1B engines, Pegasus is positioning itself to absorb future cost shocks, from fuel price swings to carbon charges, without tearing up its low‑cost formula.
How the €3–5 billion estimate stacks up
Market list prices for a LEAP‑1B engine sit in the €12–14 million range. Airlines seldom pay that amount. Large, repeat customers with long histories, such as Pegasus, typically negotiate discounts reported around 40–50% off catalogue.
On that basis, industry specialists estimate a rough value of €1.8–2.4 billion for the 300 firm engines alone. The real economic weight arrives once spare engines and decades of maintenance are included.
Over 20–30 years, service and support contracts can equal, or even exceed, the initial engine sale.
That is how analysts reach the €3–5 billion bracket: a combination of discounted engine deliveries, spare units, and a multi‑decade maintenance pipeline intertwined with Pegasus’s operations.
CFM’s grip on the single‑aisle market
CFM International — a joint venture between France’s Safran Aircraft Engines and GE Aerospace — already dominates the single‑aisle market. More than 4,000 LEAP engines have been delivered, making it the fastest‑ramping programme in commercial aviation history.
The company’s narrow‑body share draws on a simple mix: clearly measurable fuel savings, a strong reliability record, and a flexible maintenance ecosystem that airlines and independent providers can plug into.
Where CFM stands against its rivals
Industry estimates for 2025 highlight that dominance:
| Segment | Manufacturer | Estimated market share | Main programmes |
|---|---|---|---|
| Single‑aisle jets | CFM International | ~70–75% | CFM56, LEAP‑1A, LEAP‑1B, LEAP‑1C |
| Pratt & Whitney | ~25–30% | PW1100G, PW1500G, PW1900G | |
| Others | <5% | Niche and ageing fleets | |
| Wide‑body jets | Rolls‑Royce | ~50–55% | Trent XWB, Trent 7000, Trent 1000 |
| GE Aerospace | ~35–40% | GE90, GEnx | |
| Pratt & Whitney | ~10–15% | PW4000 (declining fleets) | |
| Total commercial aviation | CFM International | ~45% | Strength in single‑aisle jets |
| Rolls‑Royce | ~30% | Focus on wide‑bodies | |
| GE Aerospace | ~15% | Large installed base | |
| Pratt & Whitney | ~10% | Presence on A320neo |
Deals like Pegasus’s reinforce this structure, funnelling thousands of additional engine shop visits and spare‑parts orders to CFM across coming decades.
What long‑term maintenance really means for an airline
For many carriers, the most complex part of engine procurement is not the hardware itself but the service model wrapped around it.
Long‑term maintenance agreements often work a bit like an extended warranty blended with an insurance policy. Airlines pay per flight hour or per cycle, and the engine maker takes on part of the risk of unexpected failures and heavy shop visits.
This brings several advantages:
- Predictable cash flow instead of sudden multi‑million‑euro repair bills
- Better planning of aircraft downtime thanks to scheduled overhauls
- Access to software updates and upgraded parts over the contract life
The flip side is reduced flexibility to switch providers mid‑stream, since the maintenance deal ties the airline to a specific support network. Pegasus’s decision to lock in with CFM reflects a bet that the partnership will keep costs under control while supporting aggressive growth.
How this shapes fares, emissions and future fleets
For passengers, orders like this mostly show up in indirect ways. More efficient engines help airlines keep fares competitive when fuel prices rise, because fuel is one of the largest operating costs on each flight.
On the environmental side, a 15% cut in fuel burn does not make aviation green, but it reduces emissions per passenger compared with older jets. That matters as Europe expands carbon pricing and noise rules around airports tighten.
For aircraft manufacturers, the Pegasus deal sends another signal: single‑aisle jets powered by high‑efficiency engines will remain the backbone of short‑ and medium‑haul travel for decades, even as hydrogen and full‑electric concepts remain distant.
Any traveller booking a low‑cost flight from Istanbul to Europe in the 2030s stands a strong chance of sitting in a 737‑10 powered by LEAP‑1B engines built with French technology and supported by a contract signed this decade.
