CMR and ASA has CMR and ASA scope, respectively. Neither was ever violated. TSA has TSA scope, which was violated according to most common sense interpretations of their contract. However, They didn't have 100% holding company scope, just 100% TSA scope. They got screwed by an arbitrator because they had a small hole in their scope.
Mesa didn't need to file a Freedom grievance, because they settled their contract to finally gain 100% holding company scope, thus eliminating their management's ability to whipsaw them. They can still be whipsawed by Delta and United (and other) managements of course, but they never had any scope with them.
The ownership of all outsourced flying rests with the companies and pilot groups that allow that flying to be outsourced. CMR, ASA, TSA and Mesa don't own one minute of their Delta, United, USAirways, American or any other flying. Never did. Legacy managements and/or legacy pilots are perfectly free to call in that flying any time they want when your company's outsource ACMI contract is up.
You have every right to all ASA flying, but no right to any Delta flying. Sadly, you don't even have the right to all SkyWest flying until and unless you negtiate 100% holding company scope. If you do, you will then own all SkyWest flying, which means all EV and OO code. You will never, EVER own one seat or one minute of DL or UA code.
You fly jets painted in someone else's colors by the temporary grace and permission of other company managers and pilot groups. Any outsource provider is free to break away from those terms and go it alone, ala Independance Air.
