Just to be fair, RA wasn't reponsible for any of these contracts. That was on Gerald Grinstein's watch. RA has had to deal with them and do what he can to shed them. Freedom didn't live up to it's part of the contract which gave Delta it's first contract to cancel. They offered to pay off MAG to cancel Freedom's contract, but JO gave them the finger, so Delta canceled anyways. They were able to buy off Xjet's contract and Big Sky went belly up.
Delta has already come up with a cost and plan for cancelling Chautauqua and S5's contract. If the stockholders are indeed on RA's butt, then I'd look for some contract cancellations in March when Chautauqa and S5's contract can be cancelled. Delta might have to take on the leases on those aircraft if BB pushes for it per the contract. SkyWest is safe and ASA is pretty safe, until those performance milestones come due. If I remeber correctly have to make themselves cheaper than Compass and Mesaba to stay in the game.
