I think it is unrealistic to expect scope to be tightened to CAL's standards. It is what every pilot wants, but it would be far too costly to cancel the 70 seat contracts with RAH, GoJet, Skywest, etc.
What I would like to see is the 70+ seat fleet capped where it is at and then a deal worked out where 100 seaters go to mainline. Even that though would be hard to pull off.
Best of luck to CAL/UAL pilots.
