Elaborate as to what flying has been shifted. Specifically where UAL has been harmed by flying actually taken from UAL and given to CAL where there has been no reciprocity. Whatever you can come up with will in no way match the loss of CA seats with the ISL on the aircraft that were ordered BEFORE 10/1/2010.
Seriously? You haven't noticed that LUAL 757s are being retired and replaced with LCAL 737s? This has been going on for a while; you'd have to be unconscious to not notice.
As far as LCAL aircraft ordered before 10/1/2010, LUAL cash is paying a large percentage for those aircraft. LUAL could have used that cash to buy their own aircraft, but there was no need to - LCAL ordered too many aircraft as a standalone airline.
