Behind the scenes of glossy aircraft orders, the real power play sits under the wings, and a fresh multibillion-euro deal has again pushed a Franco‑American engine maker to the front of the pack.
A record engine order that transforms Pegasus Airlines
Turkish low-cost carrier Pegasus Airlines has sealed what it calls the largest engine order in its history, signing for 300 LEAP‑1B engines with CFM International. The agreement includes spare engines and a long-term maintenance package, turning a simple purchase into a strategic partnership that will stretch over decades.
This engine contract mirrors the airline’s huge aircraft decision announced a year earlier: a December 2024 deal for 100 Boeing 737‑10 jets, the largest aircraft order Pegasus has ever placed. The new engines and new aircraft are tightly linked, and together they signal a step change in how Pegasus plans to compete on regional and medium-haul routes.
By locking in both engines and long-term support, Pegasus is effectively prepaying for operational resilience over the next two to three decades.
For a budget carrier where every minute of ground time erodes margins, unplanned maintenance can ruin schedules and profits. Securing engines and support upfront gives Pegasus more control over availability, costs and future capacity at the exact moment its fleet is about to scale up dramatically.
The French giant behind CFM’s success
CFM International is a 50–50 joint venture between US group GE Aerospace and France’s Safran Aircraft Engines. While the brand is shared, the programme is a core pillar of Safran’s business and one of the most profitable Franco‑American collaborations in industrial history.
Safran designs and builds major parts of the LEAP engine, including the fan module and key hot-section technologies. Revenue flows not only from engine sales but from spare parts and service contracts that often last 20 to 30 years. That financial profile explains why each new long-term deal, such as the Pegasus agreement, is closely watched by investors in France.
Industry estimates suggest the overall Pegasus–CFM package, including maintenance, could be worth between €3 billion and €5 billion over its lifetime.
The range reflects typical practice for large fleet deals. List prices for LEAP‑1B engines stand around €12–14 million each, but airlines that order in bulk and maintain long-term partnerships usually negotiate discounts of 40–50%. When spares are added and service contracts factored in, the value of after-sales support can equal or even exceed the initial sale of the engines themselves.

An old partnership between Pegasus and CFM
Pegasus is not a newcomer to CFM technology. The airline grew up with the CFM56 family, progressing through several variants as it renewed its fleet: CFM56‑3, then CFM56‑5B and CFM56‑7B. That long track record set the stage for an early bet on the LEAP generation.
In fact, Pegasus holds a small but significant milestone. It was the first airline anywhere in the world to operate LEAP engines in commercial service, flying a LEAP-powered jet between Istanbul and Antalya in July 2016. That early entry gave its operations and maintenance teams years of hands‑on experience with the new architecture before many rivals.
Leap‑1B: built for hard, low-cost use
The LEAP‑1B that will power Pegasus’s Boeing 737‑10 jets is not a minor tweak on the CFM56. It brings a raft of new technologies:
- Fan blades made from composite materials, cutting weight and improving efficiency
- Ceramic matrix composites in hot sections, allowing higher temperatures and better fuel burn
- Advanced health-monitoring systems that track engine condition in real time
CFM says the design yields around 15% lower fuel consumption and roughly 15% less CO₂ emissions compared with previous-generation engines powering similar aircraft. Noise footprints also shrink, which matters as noise regulations tighten at busy airports.
Most crucially for Pegasus, the LEAP‑1B is built to cope with punishing utilisation: short turnaround times, frequent cycles, and aircraft that may fly from early morning to late at night with minimal downtime. That profile fits the business model of low-cost carriers that squeeze revenue from every available block hour.
Boeing 737‑10: more seats, lower cost per passenger
The Boeing 737‑10 is the largest variant of the 737 MAX family. With capacity up to around 230 passengers, it lets airlines add seats on popular routes without necessarily adding more flights.
For Pegasus, using a larger aircraft can lower cost per seat. Spreading fixed costs such as crew, navigation and airport fees over more paying passengers improves unit economics. On crowded medium-haul routes from Turkey into Europe or the Middle East, this can tilt the competitive balance in markets where ticket prices are extremely sensitive.
In that equation, the LEAP‑1B becomes a central ally. Its fuel efficiency and reliability help contain operating costs as the airline stretches capacity. That combination of bigger aircraft and efficient engines is key to keeping fares attractive while still generating cash for future growth.
A young fleet as a structural advantage
Pegasus already boasts one of the youngest fleets in global commercial aviation, with an average age of about 4.9 years. Such a young profile brings multiple benefits: lower fuel burn, fewer unscheduled repairs and easier compliance with progressively stricter environmental rules.
By betting on new 737‑10 aircraft and LEAP‑powered jets for the coming years, the airline deepens that structural edge. It gives Pegasus a buffer against future regulatory shocks, such as higher carbon pricing or tougher noise limits, while also supporting higher reliability in day‑to‑day operations.
How CFM dominates the single-aisle engine market
CFM International already leads the global single-aisle engine segment by a wide margin. Its CFM56 family powered generations of Boeing 737 and Airbus A320 jets. The successor LEAP line continues that dominance on new aircraft types.
By 2025, more than 4,000 LEAP engines had been delivered, making it one of the fastest rollouts for any commercial engine programme. Airlines have bought into a relatively simple promise: measurable fuel savings, proven reliability and a broad maintenance ecosystem that lets them find support almost anywhere they fly.
The competitive map in civil aviation engines looks like this:
| Segment | Engine maker | Estimated market share | Key engine programmes |
|---|---|---|---|
| Single-aisle jets | CFM International | around 70–75% | CFM56, LEAP‑1A, LEAP‑1B, LEAP‑1C |
| Pratt & Whitney | around 25–30% | PW1100G, PW1500G, PW1900G | |
| Others | under 5% | Niche products and older fleets | |
| Widebody jets | Rolls‑Royce | around 50–55% | Trent XWB, Trent 7000, Trent 1000 |
| GE Aerospace | around 35–40% | GE90, GEnx | |
| Pratt & Whitney | around 10–15% | PW4000 (declining fleets) | |
| Total commercial aviation | CFM International | around 45% | Strength in single-aisle aircraft |
| Rolls‑Royce | around 30% | Leadership in widebody engines | |
| GE Aerospace | around 15% | Large installed base | |
| Pratt & Whitney | around 10% | Strong slot on Airbus A320neo |
This dominance in the high-volume single-aisle segment explains why deals like the Pegasus order weigh heavily. Each fresh commitment reinforces CFM’s installed base, and with it, decades of steady aftermarket revenue.
What a long-term engine contract really buys
When airlines sign long-term maintenance deals, they do more than outsource repairs. They are effectively buying predictability.
In a power-by-the-hour style agreement, an airline typically pays a fixed rate per flight hour or per cycle. CFM, in return, takes on the risk of heavy overhauls, parts replacement and complex repairs. For a carrier such as Pegasus, this means fewer financial shocks when an engine needs major work.
There are trade-offs. Locking into one provider can reduce flexibility to shop around for cheaper third‑party repairs later on. Some low-cost carriers prefer to keep more control over maintenance, especially as fleets age and independent repair shops gain experience. Yet for young fleets and advanced engines, most airlines still lean toward manufacturer-backed support because access to the latest updates and parts remains critical.
Key terms that shape the deal
Several notions help explain why this contract hits the €3–5 billion range:
- List price vs. net price: Official catalogue prices for engines set a high anchor point. The actual price paid by a large customer after discounts can be almost half that figure.
- Lifetime value: An engine might be delivered once, but it will be repaired, monitored and upgraded over 20–30 years. This long tail of activity often brings in more revenue than the initial sale.
- Utilisation profile: Low-cost carriers fly their aircraft intensively. High utilisation generates more maintenance events and more billable work, which inflates the economic weight of the contract over time.
For Pegasus, the upside lies in smoother budgeting and the ability to scale its network without constantly worrying about technical surprises. For Safran and GE, the prize is a locked‑in revenue stream running well into the 2040s.
Risks and scenarios for the years ahead
The Pegasus–CFM deal still faces the usual aviation uncertainties. Traffic can slump, as seen during the pandemic. Fuel prices swing. Regulatory pressure on emissions grows year by year. If CO₂ costs rise sharply, even a 15% fuel saving might not feel enough, pushing airlines to accelerate fleet renewal again or seek alternative fuels.
There is also technological pressure. New propulsion concepts, from open‑rotor designs to hydrogen‑ready architectures, are under study in Europe and the US. Should a radically different engine appear on the market in the 2030s, airlines tied to existing generations will need to weigh the cost of early replacement against squeezing every last hour out of today’s assets.
For now, though, single-aisle jets powered by engines like the LEAP‑1B remain the backbone of global aviation. As orders like Pegasus’s show, that backbone is still being reinforced with very large cheques – and a French industrial champion stands right at the centre of the deal table.
