Wizz Air has signed a firm contract for an additional 75 A-321neo Family aircraft, taking its total order for the largest member of the Airbus single aisle to 434, and for carrier’s A-320 Family overall to 565 aircraft. 

The airline is an all Airbus operator with a fleet of over 180 A-320 Family aircraft currently in operation.
 
The A-321neo is the largest member of Airbus’ A-320neo Family. By incorporating new generation engines and Sharklets, the model brings a noise reduction and fuel savings and CO2 reduction compared to previous generation single-aisle aircraft. To date nearly 5,200 A-321neos have been ordered by customers across the globe.
