Delta's in bankruptcy, that's what gives. They got to void their contracts which is allowing them to recall at less $, and they don't have to pay the bills until the emerge, which I'm sure management is postponing as long as possible to pump up their bonus' for leading the company through and out of chapter 11. I think the whole bankruptcy deal was just to renegotiate all their contracts and debt, as I am not sure how a broke company can purchase 13 new jets and expand? Plus there announced expansion is taking on the LCC's head to head....
If I was a Delta creditor, I'd vote for the USAirways buyout - at least I know I'll get some of my investment back. Not sure if that plan is better for the pilots or not though.
