WOW this is pathetic. Xjet gets some flying and its they undercut us. Though I am not a big fan of express jet because of how I have been treated in CLE by them (nothing like being flicked off by them as you sit to go to LGA), I am glad to hear that they got some more work and some of their guys will be back online.
Did they undercut air wisconsin, probably. Was it the pilots fault. HeII no. The Xjt managment probably figured it would be better to sacrifice some profit in order to get the work. Air Wisconsin as some one else stated, would have aquisition costs that would have to be passed on to United as they dont have that many airplanes sitting around. This is all a managment function and has nothing to do with the pilots from either group.
As far as ontime percentage goes, comparing CHQ for ontime with Xjet without data that shows per airport is useless. If you want to know how reliable the carrier is, look at the departure board on any given day and see who is running on time the most. CHQ, RW, and S5 do have a higher ontime performance than the other code shares for their respective major express operations.
