Wizz Air Plans to End Engine Groundings by 2027 Amid Pratt Whitney Crisis
Wizz Air targets 2027 to resolve engine groundings caused by Pratt & Whitney GTF issues, impacting operations and finances across the aviation sector.
Wizz Air Aims to End Engine-Related Groundings by 2027 Amid Ongoing Pratt & Whitney Turbofan Crisis
Wizz Air’s announcement that it expects to end engine-related aircraft groundings by the end of 2027 marks a critical juncture in the airline’s ongoing struggle with a manufacturing crisis that has disrupted the global aviation industry. The statement from Chief Financial Officer Ian Malin signals both hope and realism in the face of persistent issues with Pratt & Whitney’s geared turbofan (GTF) engines, which have grounded hundreds of aircraft worldwide. The root cause, defective engine components produced with contaminated powdered metal, has forced airlines to overhaul operational strategies, fleet management, and financial planning, while also prompting a broader industry reckoning with supply chain risks and maintenance practices.
The implications of this crisis are far-reaching. Airlines have been compelled to adapt quickly, manufacturers are under pressure to restore confidence and operational reliability, and the competitive dynamics within the commercial aviation sector have shifted. As Wizz Air and its peers navigate these challenges, the industry is witnessing an accelerated evolution in maintenance practices, risk management, and customer support frameworks. Understanding the genesis, scale, and ongoing response to the GTF engine crisis is essential for grasping its impact and the path to eventual resolution.
The Genesis and Scale of the Pratt & Whitney GTF Crisis
The Pratt & Whitney PW1000G geared turbofan engine was introduced as a breakthrough in aviation technology, promising significant improvements in fuel efficiency and noise reduction. However, a critical flaw was discovered: contaminated powdered metal used in manufacturing certain engine components between late 2015 and 2021. This contamination resulted in microscopic defects, particularly in the high-pressure turbine disks, which could develop into dangerous cracks and potentially cause uncontained engine failures.
The full extent of the problem became apparent in 2023, when Pratt & Whitney expanded its recall to include all 3,000 PW1100G engines in service globally. These engines power a substantial portion of the Airbus A320neo family, creating a ripple effect across airlines that rely on this aircraft type. The recall required lengthy inspections, each taking up to 300 days, and led to an average of 350 aircraft being grounded at any given time through at least 2026, with the highest concentration of groundings in early 2024.
Financially, the crisis has been monumental. RTX, Pratt & Whitney’s parent company, estimates the total cost, including unscheduled work, replacement parts, and operator compensation, at $6 to $7 billion. RTX itself expects to pay $2.9 billion in compensation to affected customers, reflecting the scale and complexity of the recall. These costs represent one of the largest product recall events in aerospace history and have had a material impact on both manufacturers and operators.
“The recall’s magnitude is unprecedented, requiring inspections that take between 250 to 300 days to complete, leading to an average of 350 airplanes being grounded through 2026.”
Wizz Air’s Operational and Financial Challenges
Wizz Air stands out as one of the most affected airlines, with its operational model and fleet composition making it particularly vulnerable to the GTF engine disruption. As of mid-2024, the airline had 41 aircraft grounded due to engine issues, approximately 15% of its total fleet. Although this number has since declined to 38, it remains a significant operational constraint, especially for a carrier built on high utilization and rapid growth.
To mitigate the disruption, Wizz Air has doubled its spare engine pool and overhauled maintenance cycles. The airline has also shifted its approach to fleet planning, emphasizing tighter collaboration with Pratt & Whitney and more predictive, data-driven maintenance strategies. These adjustments have exposed structural weaknesses in the engine aftermarket and placed additional pressure on both internal and external maintenance resources.
The financial impact has been severe. For the year ending March 2025, Wizz Air reported a 41.5% year-over-year drop in net profit to €213.9 million, while operating profit fell by 62% to €167.5 million. Despite a modest rise in annual revenues to €5.3 billion, non-fuel unit costs surged nearly 20%, largely due to increased maintenance, repair, and material expenses. The crisis has also forced Wizz Air to reduce its annual passenger growth target and delay new aircraft deliveries, constraining both its short-term flexibility and long-term expansion plans.
Strategic Pivots and Network Restructuring
Wizz Air has responded to the crisis by fundamentally rethinking its network and fleet strategy. The airline recently exited the Abu Dhabi market, citing geopolitical risks and environmental factors that worsen engine wear. Aircraft previously based in Abu Dhabi have been redeployed to European routes, while older A320ceo models are being parked during off-peak periods to conserve maintenance resources.
This strategic shift reflects a broader move toward maintenance flexibility and risk mitigation. By pausing utilization of older, less efficient aircraft, Wizz Air is prioritizing operational resilience over aggressive growth. The airline’s ability to rapidly adapt its network and fleet utilization has been tested, forcing a shift from opportunistic expansion to a more conservative, maintenance-driven approach.
The network restructuring has also affected Wizz Air’s competitive positioning. Reduced operational flexibility has limited the airline’s ability to capitalize on new market opportunities, a key advantage for low-cost carriers. Instead, Wizz Air is now dependent on the timely completion of engine repairs and long-term planning with manufacturers and maintenance partners.
“The airline has been compelled to double its spare engine pool and reconfigure maintenance cycles, creating mounting pressure on internal planning and third-party maintenance, repair, and overhaul partners.”
Financial Performance and Credit Implications
The ongoing engine crisis has placed significant strain on Wizz Air’s financial position and creditworthiness. In July 2025, Fitch downgraded the airline’s credit rating from BB+ to BB, citing weaker operating performance as a direct result of the engine issues. Despite some revenue growth, the airline’s profitability and cost structure have been fundamentally altered by increased maintenance expenses and lost capacity.
Other airlines have faced similar challenges. Spirit Airlines, for example, has negotiated compensation agreements with Pratt & Whitney, including monthly credits through 2025. These arrangements provide some financial relief but require airlines to release further claims, locking in both parties to a defined compensation structure while the repair program continues.
For manufacturers, the crisis has forced accelerated investment in maintenance, repair, and overhaul (MRO) capacity and technological innovation to reduce repair times. RTX has expanded its MRO network, including new partnerships with Delta TechOps and MTU Aero Engines, and is deploying additive manufacturing techniques to speed up repairs and reduce costs.
Industry-Wide Impact and Technical Details
The GTF engine crisis has affected airlines worldwide, not just Wizz Air. Spirit Airlines has seen up to 30% of its A320neo-family fleet grounded, while Indian carrier GoFirst suspended operations and filed for bankruptcy, directly attributing its collapse to engine reliability problems. Swiss and Air Baltic have also grounded portions of their A220 fleets due to related engine issues, and EgyptAir sold its entire A220-300 fleet because of persistent reliability challenges.
The technical challenges stem from both the contaminated powdered metal issue and other design flaws. The GTF engine’s innovative geared design enables higher efficiency and lower noise but also introduces new failure modes. In addition to the powdered metal contamination, earlier problems included knife edge seal failures and excessive corrosion in high-pressure compressor components, further complicating maintenance and reliability.
Pratt & Whitney’s response has included a comprehensive fleet management plan, expanded MRO capacity, and significant investment in new repair technologies. The company’s compensation framework, valued at $6–7 billion, is one of the largest in aerospace history and includes direct payments, credits, and support to affected airlines. These measures aim to restore operational reliability and rebuild customer confidence, but the resolution timeline extends into 2027, with ongoing risks and uncertainties.
“The crisis has accelerated broader industry trends toward maintenance digitization and predictive analytics. Airlines are investing heavily in data-driven maintenance approaches and closer collaboration with engine manufacturers.”
Future Outlook and Industry Implications
The path to recovery will be gradual. Wizz Air’s goal of ending engine-related groundings by 2027 is ambitious but reflects the current pace of repairs and capacity expansion. As of early 2024, the number of grounded aircraft industry-wide peaked at around 650 before stabilizing at 300–350, where it is expected to remain until 2026. Pratt & Whitney has reported a modest improvement in engine turnaround times, but the repair backlog remains substantial.
Looking ahead, the crisis is likely to influence engine selection, fleet planning, and risk management strategies for years to come. Airlines may prioritize supply chain diversity and avoid overreliance on single-source engine suppliers. Meanwhile, the adoption of predictive maintenance and advanced repair technologies could improve long-term operational resilience and efficiency. The experience has also underscored the importance of robust quality control in aerospace manufacturing and the potential consequences of supply chain lapses.
Conclusion
The Pratt & Whitney GTF engine crisis stands as a defining challenge for the aviation industry, highlighting vulnerabilities in manufacturing, maintenance, and supply chain management. Wizz Air’s projection that it will resolve engine-related groundings by 2027 provides a roadmap for recovery, but the journey involves ongoing operational, financial, and strategic adjustments. The crisis has forced airlines to rethink growth strategies, invest in maintenance capabilities, and collaborate more closely with manufacturers.
Ultimately, the lessons learned from this episode will shape the future of aircraft design, manufacturing standards, and airline operations. While the costs have been high, both financially and operationally, the industry’s response demonstrates resilience and a commitment to safety and reliability. As the sector moves forward, the innovations and adaptations born out of necessity may yield long-term benefits, strengthening the foundations of global aviation.

easyJet to Install Starlink Wi-Fi Across Its Entire Fleet
easyJet will equip 350+ Airbus aircraft with Starlink internet starting in 2027, its first inflight connectivity offering.
easyJet (U2) will equip its entire fleet of more than 350 Airbus aircraft with Starlink satellite internet, marking the first time the European low-cost carrier will offer inflight connectivity to its passengers.
In a press release issued on October 26, 2026, the airline confirmed that the hardware rollout will begin in the first half of 2027 and is expected to be completed by early 2028. The agreement aligns easyJet with a growing industry shift toward low-Earth orbit satellite Wi-Fi and introduces a new competitive dynamic among European budget operators.
Fleetwide deployment and passenger experience
The installation program will cover easyJet’s existing fleet of Airbus A320, Airbus A320neo, and Airbus A321neo aircraft. Once activated, the Starlink system will allow passengers to stream entertainment, play games, browse the internet, and check flight status directly from their seats. The airline also indicated the connectivity could eventually enable passengers to order from the inflight menu via their personal devices.
Kenton Jarvis, Chief Executive Officer (CEO) of easyJet, emphasized the importance of the agreement for the airline’s customer base:
“Innovation is in easyJet’s DNA and partnering with SpaceX to bring Starlink’s high-speed internet connectivity onboard for the first time will not only further enhance the experience we provide millions of customers, but means we are offering more of the options both business and leisure travellers want when they choose who they fly with.”
SpaceX President and Chief Operating Officer (COO) Gwynne Shotwell noted that the system will provide fast, reliable connectivity from takeoff to landing, allowing passengers to work or stay in touch without interruption.
Shifting the European low-cost carrier model
Historically, easyJet has avoided offering inflight Wi-Fi. This approach aligned with a traditional low-cost carrier model that eschews ancillary amenities requiring heavy infrastructure investment, prioritizing low fares and fast turnaround times. The airline, which carried 100 million passengers in 2025, operates a point-to-point network of over 1,200 routes connecting 160 airports across 35 countries.
The decision to invest in Starlink follows a similar move by European budget competitor Wizz Air (W6), which signed an agreement for the satellite service in June 2026. According to reporting by Business Insider, the dual adoption by easyJet and Wizz Air leaves Ryanair (FR) as the only major European budget carrier without an inflight Wi-Fi offering. Ryanair CEO Michael O’Leary has previously criticized the technology, arguing in January 2026 that passengers are unwilling to pay for internet on short flights and noting that the aerodynamic drag of the external antenna adds to fuel costs.
Globally, Starlink has rapidly expanded its footprint in commercial aviation. American Airlines (AA) announced a partnership in May 2026 to install the system on over 500 narrowbody aircraft starting in the first quarter of 2027. Qatar Airways (QR) reached a milestone of 150 Starlink-equipped widebody aircraft in August 2026, while United Airlines (UA), Air France (AF), and Hawaiian Airlines (HA) have also adopted the technology.
AirPro News analysis
We view easyJet’s adoption of Starlink as a definitive turning point for passenger expectations in the European short-haul market. By committing to fleetwide connectivity, easyJet and Wizz Air are effectively isolating Ryanair’s position that Wi-Fi is an unnecessary expense for flights averaging under two hours. However, a critical detail remains unconfirmed: easyJet has not specified whether the Starlink service will be complimentary or structured as a paid ancillary. While full-service carriers like United Airlines and Qatar Airways are leveraging Starlink as a free product to drive brand loyalty, low-cost carriers typically monetize such additions. If easyJet charges for access, the uptake rates will provide a clear test of O’Leary’s assertion that budget passengers will not pay for connectivity on short sectors.

IndiGo and Air India Express to Shift Flights to Navi Mumbai Airport
IndiGo and Air India Express begin phased moves to NMIA from Dec 2026, enabling CSMIA Terminal 1 redevelopment by 2030.
IndiGo and Air India Express will begin shifting domestic and international flights to the newly constructed Navi Mumbai International Airport (NMIA) starting in December 2026, resolving a slot dispute and clearing the way for a major redevelopment of Mumbai’s existing aviation infrastructure.
The phased transition, announced in a joint press release by the airlines and Adani Airport Holdings Limited (AAHL) on October 25, 2026, operationalizes Mumbai’s dual-airport system. The move frees up critical capacity at Chhatrapati Shivaji Maharaj International Airport (CSMIA) to allow for the structural overhaul of Terminal 1 by 2030 while preserving historical operating slots for the carriers.
Phased transition timeline and route details
The operational shift will occur in stages, beginning with domestic services. Hindustan Times reported that Air India Express will commence operations at NMIA in December 2026 with four daily domestic flights. The carrier plans to introduce international services to Kuwait and Oman from the new airport in January 2027, subject to pending regulatory approvals. By the IATA Northern Summer 2027 season, Air India Express is expected to complete the transition of its West Asia services, including flights to Jeddah, Riyadh, Dammam, Doha, Muscat, and Sharjah.
IndiGo will commence its international operations from NMIA in February 2027. Between February and July 2027, the carrier will progressively transfer 12 daily international departures from CSMIA to the new facility. By July 2027, IndiGo will serve 12 international destinations from NMIA, comprising 11 transferred routes and one new daily service to Kathmandu.
The transferred IndiGo routes will include services to Bahrain, Riyadh, Dammam, Jeddah, Madinah, Kuwait, Ras Al Khaimah, Fujairah, Muscat, Dhaka, and Jakarta.
The phased transition is intended to support a transparent, equitable and proportionate rebalancing of capacity across Mumbai’s dual airport system, taking into account each airline’s presence at CSMIA.
The joint statement from IndiGo and AAHL noted that this balanced approach will facilitate an orderly transition, minimize operational disruption, and provide planning certainty for airlines and passengers as NMIA scales up its operations.
Resolving the Mumbai slot dispute
The transition agreement follows weeks of negotiations between airline operators and AAHL regarding capacity constraints at CSMIA. According to reporting by Mint, the Airline Operators Committee of Mumbai formally rejected an initial AAHL proposal earlier in October 2026. That proposal sought to temporarily cut 265 of the 770 weekly international departures at CSMIA’s Terminal 2 to accommodate the Terminal 1 redevelopment project.
The Ministry of Civil Aviation intervened in the standoff, leading to the phased relocation compromise announced by IndiGo and Air India Group. While the Indian carriers have formally agreed to the transition, Mint noted that earlier reports indicated ongoing resistance from several foreign carriers regarding the relocation of their international flights to NMIA. It remains unconfirmed if foreign carriers will be mandated to shift operations.
Infrastructure expansion and CSMIA Terminal 1 redevelopment
CSMIA has operated under severe capacity constraints for years, necessitating the structural redevelopment of Terminal 1. According to The Hindu, the T1 redevelopment project is designed to modernize passenger facilities, upgrade safety systems, and increase the terminal’s annual capacity by 33 percent, growing from 15 million to 20 million passengers. The target completion date for the redevelopment is 2030.
Navi Mumbai International Airport, which officially welcomed its first passengers on December 25, 2025, was developed as a greenfield project specifically to relieve congestion at CSMIA. The Hindu reported that NMIA features an initial annual passenger capacity of 20 million, with future expansion phases planned to accommodate up to 90 million passengers annually. The facility incorporates automated baggage handling, digital passenger-processing systems, and multimodal transport links to the broader Mumbai Metropolitan Region.
AAHL, a wholly-owned subsidiary of Adani Enterprises Limited, is India‘s largest operator of Public-Private Partnership airports, managing eight facilities across the country. In September 2026, the company secured approximately $1 billion in primary equity capital from a consortium of global investors, including Temasek and BlackRock, at an $18 billion valuation. The capital is earmarked for airport modernization and capacity expansion to serve 200 million passengers annually across the AAHL portfolio.
IndiGo’s international growth strategy
The transition of flights to NMIA aligns with IndiGo’s broader fleet and network strategy. As India’s largest airline by market share, IndiGo is currently executing a major international expansion. The carrier is preparing to induct long-range Airbus A321XLRs and widebody Airbus A350s to reach deeper into Asia, Africa, and Europe.
Shifting a portion of its international departures to NMIA allows IndiGo to continue its aggressive 2027 international expansion using its incoming Airbus A320, A321, and A321XLR fleet without exacerbating the existing slot constraints at CSMIA. IndiGo stated it will announce the exact dates for the transition of individual services to NMIA once final project coordination is complete and relevant operating approvals are secured.
AirPro News analysis
The successful operationalization of a dual-airport system in Mumbai represents a critical milestone for Indian aviation infrastructure. The compromise brokered by the Ministry of Civil Aviation avoids a damaging capacity reduction at CSMIA that would have severely impacted international connectivity and airline revenues. For IndiGo and Air India Express, securing a strong early foothold at NMIA provides the runway needed for their respective fleet expansions, turning a potential infrastructure bottleneck into a strategic growth opportunity. The lingering question is how AAHL and the civil aviation ministry will manage foreign carriers, who have historically resisted moving operations away from established primary hubs.
