I keep on hearing how SKW has "economy of scale", I was under the impression that to have economy of scale the carrier must already operate the type of aircraft that is being used. SKW does not operate ANY Embraer jets! The EMB-175 is a COMPLETELY different airframe than they operate. To start operations using the EMB-175 they would have to have an approved training program for pilots and FAs. In addition they would have to catelog parts and supplies for said airframe. Not only that, but their MTX personnel and Dispatchers would have to complete training for a new aircraft type. No matter how you look at it, it's almost always more expensive to carry another airframe type. The EMB-170/175 share very little if anything with the CRJs. Please correct me if I'm wrong...
