Wizz Air has exercised options to purchase 75 new generation Airbus A321neo aircraft.
The move comes as the eastern and central European budget carrier sets its sights on expanding its fleet from 165 to 500 aircraft by the end of the decade.
Delivery dates of the 75 new Airbus types is subject to agreement between the airline and the manufacturer and is subject to shareholder approval.
The development follows Wizz Air agreeing to acquire a total of 102 aircraft from Airbus in November 2021, including 75 A321neos plus purchase rights for up to a further 75 for delivery in 2028-29.
The carrier has now exercised those purchase rights.
Chief executive Jozsef Varadi said: “The combination of Wizz Air’s ultra-low cost operation and the market-leading Airbus A321neo aircraft together create a strong platform for Wizz Air’s future growth in the coming decade as we further strengthen our position as one of the world’s most sustainable airlines.
“We remain on track to become a 500 aircraft airline group by the end of the decade while delivering our commitment to reduce our already industry-leading CO2 emissions by 25% by 2030.”
