From what I understand, two of three unions have proposals before the company. The IBT has not as far as I know.
I still think that Delta's intention is to shut us down; though I am sure they would love to get a very favorable contract from pilots, what pilots do means nothing if the others don't play ball.
Here's how I would handicap this: 65% chance we are shut down outright. 20% chance of some sort of hybrid arrangement that calls for some airplanes/crews to go elsewhere. 15% chance of new contract with drastically low rates (lower than gojets) and hope for expansion.
Of course, Comair could merely be a stalking horse to used in negotiations with Pinnacle.
