I think the fact remains that regardless of the BK outcome, Mesa will have no future feed contracts, either new or renewed. Those carriers they haven't directly alienated are sure not to place their businesses in potential jeopardy by relying on this company, new management or not.
With so many other feeder choices out there, its a no-brainer. Current MAG pilots should evaluate the length of the feed contract that provides their income and expect that to be the duration of their MAG employment unless they can bump into a longer contract until that ends.
That would be the prudent thing to do.
