Along with GE and Rolls-Royce, Pratt & Whitney is one of the giants dominating the commercial jet engine market. However, its normally excellent reputation for cutting-edge engines has been beset with issues from the Pratt & Whitney Geared Turbofan (GTF) engine problems on Airbus A320 fleets. The problem is expected to affect up to 700 engines globally over the next three years. Spirit Airlines has now negotiated to receive between $150 and $200 million in compensation from International Aero Engines (IAE) for its engine troubles (IAE is a Pratt & Whitney affiliate).
