Oui, all AF 744 have GE engines. AF favours GE over PW and RR. However, half of their 767 fleet does have PW and their remaining 747-100. Yet all other fleets carry GE on their wings. And when they can't buy GE straighout (for example, their Airbus and 737 fleets) they buy CFM, a joint co-operation between GE and SNECMA (a french company specializing in airplane engines, and yes I know that CFM is the only option on the 737). I'm pretty sure that similarities are the main reason for buying a standardized fleet of engines, and in CFM's cases for nationalistic reasons (much like BA buying RR and IAE, a company helping out another company of the same country, but in BA's case they started buying RR before they were privatized, and they stuck with them). Au Revoir!
