Wizz Air says its Pratt & Whitney engine disruption is expected to continue into 2027, but its stated target is to have no aircraft grounded for the issue by the end of that calendar year. That is a company forecast, not a confirmed completion date. As of 30 June 2026, Wizz Air reported 27 aircraft grounded for GTF-related inspections, down from 41 a year earlier.
How many Wizz Air aircraft are grounded?
Wizz Air reported 27 aircraft grounded for GTF engine-related inspections as of 30 June 2026, compared with 41 at 30 June 2025. The count refers specifically to aircraft grounded for those inspections; it does not mean that every aircraft with a compatible engine, or every Airbus neo aircraft in the fleet, was affected. Wizz Air’s 2026 annual report gives the dated figures.
In results published on 6 August 2026, Wizz Air forecast 15–20 aircraft grounded at the end of F27, then zero by the end of calendar 2027. F27 is the company’s financial-year label; it is not interchangeable with calendar year 2027. Wizz Air said its end-of-2027 return-to-service plan remained on track, but the zero figure is still a forecast. Wizz Air’s investor relations results materials report the outlook.

What is causing the engine inspections?
The issue concerns the PW1100G-JM geared turbofan (GTF) engine family. Wizz Air says Pratt & Whitney service bulletins issued on 3 November 2023 led to an inspection program that began in January 2024. Inspections check whether manufacturing issues associated with powder-metal life-limited engine parts mean those parts need replacement. Wizz Air’s annual report describes the inspection program and its potential effect on the fleet.

Why could the disruption last through 2027?
Returning an aircraft to service depends on more than identifying the affected part. Wizz Air says the number of aircraft affected depends on engine utilisation, spare-engine availability and access to maintenance, repair and overhaul induction slots. It also identifies constraints on Pratt & Whitney’s capacity, spare parts and turnaround times. If engines cannot be processed or replaced quickly enough, aircraft can remain unavailable even while inspections and repairs proceed.
Those dependencies are why the end-2027 date should be read as a planning target rather than a guarantee. Wizz Air’s August 2026 statement that the plan remained on track describes management’s assessment at that time; it does not establish that all aircraft will return by the target date. The annual report sets out the capacity and supply factors affecting the schedule.

What does this mean for Wizz Air’s fleet and finances?
Fleet context
At 30 June 2026, Wizz Air reported a fleet of 270 aircraft, including 191 Airbus A321neo and six A320neo aircraft; neo aircraft made up 78% of the fleet. Those fleet-wide figures are not counts of aircraft affected by the inspections. The reported grounded count is the narrower figure of 27 aircraft grounded for GTF-related inspections. Wizz Air’s 2026 annual report provides the fleet totals.
Support agreements and costs
Wizz Air says it signed a commercial support agreement with Pratt & Whitney on 31 December 2024. It covers operational support and compensation for certain direct costs through the end of calendar 2026. A separate engine selection agreement, signed on 17 June 2025, selected GTF engines for 177 previously unassigned aircraft in Wizz Air’s Airbus orderbook and included a commitment to purchase 68 additional spare engines. These agreements do not by themselves establish how quickly grounded aircraft will return to service.

The company says financing, parking and engineering costs are only partially offset by manufacturer compensation. It also reports over-staffing and schedule volatility as engines return, and says the disruption has depressed returns. Wizz Air’s cited disclosures do not quantify a specific passenger-level delay or cancellation effect, nor do they establish an individual passenger’s eligibility for compensation. Wizz Air’s 2025 annual report describes the support agreement and engine selection agreement.
What Wizz Air has said about adding aircraft
In a report published 15 June 2026, CAPA quoted Wizz Air CEO József Váradi saying: “Our interest is to get the existing fleet fixed before we embark on a new aircraft because that will just incur capital cost”. The comment expresses the company’s stated priority for addressing the existing fleet; it is not a new timetable for completing inspections. CAPA reported the comment on 15 June 2026.

What passengers can and cannot infer
The grounded-aircraft count and the company’s financial disclosures describe fleet and business effects, not the cause of any particular passenger’s disrupted journey. The cited disclosures do not quantify how many delays or cancellations were attributable to the engine issue or determine whether an individual passenger is owed compensation. For a specific booking, check the flight’s status and Wizz Air’s applicable notice or rebooking terms rather than assuming a disruption was caused by this issue.
