If Delta didn't want anything smaller than a CRJ-700 and EMB-170 on property, is selling CPZ and Mesaba and the ensuing mess it makes the way to do it, or to start to do it?

For a while you saw 75's doing 76 trips, 73s and MD88s doing 757/737 trips, CRJ900/700s doing MD88 trips, and CRJ200s doing CRJ900/700 trips, but now do we see a reversal? A flow back the other way especially now you can plug a whole new fleet of Airbus's, 753s and DC9s into the NB mix. By the time things settle MD88s are rarely going ATL-LGA and ATL-ORF goes from nearly all RJs to all MD88s, for example.
