In Daves last address he apparently stated the company is in discussions with both Embraer and Canadair for its MAA 70 seat jet order. I would hope its the EMB, its looks much more pax friendly, like a mini-Airbus. It seems like the EMB170 family is perfectly suited for much of the east coast short haul network. It would be silly to operate both types, but I suppose like everything else its all about the better deal. I heard that Mesa is moving their CRJs to HPX ops and ERJs to USX- is US trying to have all ERJS in the Express network? But again, Midway has CRJS.
