Now not knowing many of the technicalities of the two (or more?) engine options for the 787 (General Electric GenX/RR Trent 1000) but having a huge interest in turbine engines, could someone explain to me why certain airlines would choose one and not the other, or is it just the obvious thing being financial, or is one better for different roles and environments then then the other?
From what I can see, many of the Asian carriers seem to be using GE?
