Wizz Air has said it will return to growth in 2026 after reaching a support and compensation agreement with US engine supplier Pratt & Whitney.
The London-listed airline has been hit by the grounding of planes due to engine problems, sending its shares down 35 percent this year.
Wizz Air expects 40 of its Airbus A320neo aircraft to remain grounded until 2025-26.
Pratt & Whitney will carry out the necessary checks and has agreed to compensate Wizz Air and provide operational support.
Wizz Air revealed last month that half-year operating profits fell by a third to £289.7 million.
But it hopes to return to growth in 2025-26 thanks to measures to compensate for aircraft problems.

It will receive 50 new A321neo aircraft in 2025-26, helping to expand flights by a fifth.
And its goal of expanding passenger capacity by 20 percent annually and having 500 aircraft by 2030 remains in place.
Wizz Air said: “We continue to take steps to mitigate the impact of grounded aircraft and continue to work with Pratt & Whitney to get them back up and running as soon as possible.”
