Philippine Airlines (PAL), a longtime General Electric customer, will switch to Pratt & Whitney (P&W) and Rolls-Royce (R-R) engines for its recently ordered Airbus fleets.

All of PAL’s existing widebodies utilize engines developed by GE and the airline’s current narrowbody fleet is powered by CFM, a joint venture of GE and France’s Snecma.

But industry sources tell AviationWeek PAL has chosen P&W’s International Aero Engine (IAE) V2500s to power the 34 A321s just ordered from Airbus.

These sources also say the airline has opted for P&W’s Geared Turbofan (GTF) for the 10 A321NEOs also included in the new order and R-R Trent 700s for 10 A330s-300s.

First deliveries of PAL’s new A330 are scheduled for the second half of 2013.

It is unclear why PAL decided to switch, although sources say P&W has been aggressively marketing the IAE V2500 and GTF.

In February, India’s GoAir chose the GTF engine to power A320NEOs on order, even though its current-model A320s are CFM-powered.

PAL’s spokesman was unavailable and both engine makers would not comment on the engine choices, which have not been officially announced.

Philippine conglomerate San Miguel bought 49% of PAL Holdings in April from Lucio Tan. As part of the deal, San Miguel chief Ramon Ang became president of the airline.
