The deal is for the medium-range A321neo which were a purchase option under an agreement signed in November 2021.
The original contract was for delivery in 2028 and 2029, but Wizz said this was subject to agreement with the manufacturer and Wizz shareholders.
The original deal will see 102 Airbus aircraft added to the Wizz fleet between 2025 and 2027 ahead of the latest order.
Jozsef Varadi, Wizz Air chief executive, 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.
“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."
