The E-175 is a good jet. It's significantly smaller than the MD-80 and 737 and just a bit bigger than the CRJ-700. The chances of the E-175 replacing MD-80 flying is pretty small.
If the pilots union really wants to get a deal done, they should sign off on the scope clause concession for the E-175 and Q400's in exchange for a 110-130 seat plane for mainline to replace the MD-80. Maybe something like the 737-700 or, if AA's management can be interested in the NG narrowbodies, the Bombadier C130 - which looks like a great plane on paper.
Maybe something along the lines of "for every E175 purchased, a (737-700 or C130) must also be purchased." It's just an idea. AA gets larger, more comfortable, more economical regional jets. The pilots union gets an MD-80 replacement which allays their fears of large chunks of the domestic network being "expressed" (to borrow a United term) and everyone gets a plane that burns much less gas than the MD-80. That should be a win, win, win.
I agree with you on the E-jets.
Embraer IMHO, hit a "Grand Slam Home Run", being the FIRST to come out with that "dead center/middle of the road/domestic jet !
Rarely does Bombardier get "one upped",(in their niche market)...... but they DID !!
