900s would make more sense. It is more fuel efficient than the 170/175 and the training cost is pretty much non existent. Not only for pilots but also the maintenance and flight attendants. Passengers do prefer the Embraers but we don't have enough gates in E concourse to accommodate them. But the ultimate decision may lie with bombardier and embraer. The management is whipsawing them as they are whipsawing AE and PSA and probably PDT next.
