The majority of the Eagle fleet is obsolete(ERJ135/140, ATRs), but along with that is APAs scope clause. In BK I am guessing the eventuality is an industry average scope clause, which would mean lots more CRJ700s and probably either CRJ900s or ERJ170s at regionals.

CRJ700s and 900s could be added to Eagle's fleet very easily considering they already have the CRJ700 program going, and with little disruptions since they are going through the BK process as well.
