Wizz Air has once again selected Pratt & Whitney engines to power up to 177 additional Airbus A321neo aircraft. The agreement was confirmed at the Paris Air Show on June 17, 2025, and solidifies the long-standing partnership between the two companies.
This decision is notable, as Wizz Air has recently been forced to ground large portions of its existing fleet due to unplanned maintenance on the current Pratt & Whitney engines. Nevertheless, Wizz Air CEO József Váradi emphasized the economic benefits of the GTF engines, which are said to offer "unbeatable fuel efficiency." This new order brings the total number of Wizz Air aircraft powered by Pratt & Whitney GTF engines to 453.
Long-standing partnership in the shadow of challenges
The relationship between Wizz Air and Pratt & Whitney is one built on a long history. In 2016 and 2020, Wizz Air selected Pratt & Whitney's GTF engines for a total of 276 Airbus A320neo, A321neo, and A321XLR aircraft. The recent decision to equip a further 177 Airbus A321neo aircraft with the PW1100G-JM Geared Turbofan engines underscores the company's confidence in the technology and the continuation of an exclusive partnership that dates back to 2003. Rick Deurloo, President of Commercial Engines at Pratt & Whitney, described today's announcement as "another important milestone in our long-standing relationship with Wizz Air and a vote of confidence in the GTF engine."
However, the recent decision was not without controversy. It was known that CFM International was also in the running for this lucrative contract. The choice in favor of Pratt & Whitney came despite Wizz Air's history of experiencing problems that resulted in significant operational disruptions. Reports indicate that the airline was forced to ground numerous aircraft because its existing Pratt & Whitney engines required maintenance due to a material defect, particularly in the turbine blade. This led to flight cancellations and inconvenience for passengers. The resulting capacity restrictions placed a significant operational and financial burden on Wizz Air.
Despite these difficulties, Wizz Air appears to prioritize the long-term economic benefits of GTF engines over the short-term operational challenges. József Váradi, CEO of Wizz Air, stated: "Our relationship with Pratt & Whitney has been instrumental in supporting our growth strategy, which will enable Wizz Air to have a fleet of 500 aircraft within a decade. GTF engine technology delivers the most economical solution, offering unbeatable fuel efficiency and enabling quieter flights for our passengers, as well as a lower cost base for the airline." The decision thus reflects a strategic long-term perspective that prioritizes cost efficiency and growth.
The GTF engine technology: Focus on efficiency
The Pratt & Whitney PW1100G-JM Geared Turbofan (GTF) engines are known for their innovative architecture, which uses a reduction gear between the fan and the low-pressure turbine. This technology allows the fan to rotate at a different speed than the low-pressure turbine, resulting in increased fuel efficiency and reduced noise levels. These features are critical for low-cost airlines like Wizz Air, as they directly impact operating costs and thus strengthen competitiveness.
Wizz Air currently operates a fleet of 163 A320neo Family aircraft, already equipped with GTF engines. Additionally, 73 A320ceo Family aircraft are equipped with IAE V2500 engines. Continuous investment in GTF technology solidifies Wizz Air's position as a major player in the low-cost segment and as an operator of a modern and efficient aircraft fleet. The airline pursues an aggressive growth strategy and plans to expand its fleet to 500 aircraft within a decade. The focus on fuel-efficient engines is a central pillar of this strategy, as fuel costs represent a significant portion of an airline's total costs.
The challenges Pratt & Whitney faces with GTF engine maintenance are nothing new in the aviation industry. Engine manufacturers are constantly working to improve their products and address initial issues that can arise with new technologies. The fact that Wizz Air is continuing and even expanding its partnership despite these difficulties suggests that the fundamental benefits of GTF technology are considered compelling enough to justify the temporary setbacks. However, the need for regular maintenance and the associated downtime are closely monitored by airlines and are a constant consideration in their operational planning.
Competition in the engine market and strategic implications
The market for aircraft engines is a duopoly dominated mainly by Pratt & Whitney and CFM International (a joint venture between General Electric and Safran Aircraft Engines). These two companies compete intensely for contracts with major aircraft manufacturers such as Airbus and Boeing. Choosing an engine manufacturer is a strategic decision for airlines, affecting not only the acquisition cost but also long-term operating costs, maintenance requirements, and fuel efficiency over decades.
Wizz Air's decision in favor of Pratt & Whitney is an important victory for the engine manufacturer, especially in the context of recent challenges. It could be seen as a vote of confidence in Pratt & Whitney's ability to address maintenance issues and ensure the long-term reliability of its GTF engines. For CFM International, which was also in the running for the contract, this represents a missed opportunity to strengthen its market presence with Airbus A321neo operators.
However, the strategic implications of this decision extend beyond the direct partnership. By expanding its fleet and focusing on the A321neo, Wizz Air is strengthening its position in the European low-cost segment. Due to its size and efficiency, the A321neo is a key aircraft for airlines seeking growth while minimizing operating costs. The choice of engines is a key factor in achieving these goals. The fuel efficiency of the GTF engines can help ensure Wizz Air's competitiveness in a highly competitive market and support its expansion plans.
Ryanair, a major competitor of Wizz Air, relies primarily on Boeing aircraft and engines from CFM International. The diverging engine choices of the major low-cost carriers reflect the different approaches to cost optimization and fleet strategy in the European aviation market. Despite the current challenges related to GTF engines, Wizz Air continues to position itself as an airline committed to modern, fuel-efficient technology to achieve its long-term growth objectives and offer passengers cost-effective flights. The ability to maintain a low cost base, even in the face of rising cost factors such as fuel and maintenance, will be critical to Wizz Air's future success.
