Spirit Airlines has chosen Pratt & Whitney and International Aero Engines powerplants for 75 Airbus A320s.
The PW1500G will power the 45 A320neos on order under a 75-aircraft deal finalised in February, while IAE's V2500 is engine of choice for the 30 current-generation A320s.
Deliveries of the current-generation narrowbodies are to begin in 2016 and the A320neos in 2018. Florida-based Spirit will be the first North American operator of the PW1500G, says Pratt & Whitney president David Hess.
The low-cost airline's active fleet includes V2500-powered A320s, which boosted Pratt & Whitney's chances over competitor CFM International. "The V2500 is already in operation with us. We know the value of that. It was a relationship decision as well as an economic decision," Spirit's chief financial officer Ted Christie tells Flightglobal.
Having studied both engine options for about a year, Spirit believes that its choice offers benefits "above and beyond that for CFM", says Christie.
The engine deal includes 12-year maintenance service agreements for both engine types. With spares factored in, the PW1500G order covers 90 engines and the V2500 order 64.
