Anyone who's been on 772 routes that consistently fill up could suggest other potential routes.

DFW-FRA, ORD-LHR, JFK-LHR (especially with the reduced AA capacity starting in April), possibly flights into NRT or PEK... It's all speculation, but I think we've all been on 772s elbow-to-elbow.

AA do already operate GE engines on other widebodies and have chosen them for their very-possibly-forthcoming 787-9s, so it wouldn't be entirely new ground. Indeed, across the AA fleet one would find engines from GE, Rolls, P&W
and CFMI. It would seem they don't seem put off by "diversifying" their source of engines.
