What types of performance/cost differences do the CFM56 and V2500 engines offer the A320? I am interested in understanding why a new Airbus customer like US Airways goes out and buys so many A320 family aircraft all fitted with CFMs.
The CFM56 is popular in North America, with the exception of America West, Mexicana, and United. The V2500 seems to be a more advanced engine; however, does it suffer from reliability problems? What is the dispatch reliability of CFM-powered Airbuses compares with those powered by the V2500?
Also, does anyone have any word-of-mouth reports of how pleased airlines are with their engine selections. I thought it was interesting that British Airways ordered its new A319s with V2500 power.
