Why bother with a NDA now? In the end, AMR will emerge from bk as a standalone. However, AMR management has so poisoned the well of employee relations that I do not see how the company can survive long term. I can't imagine what AMR executives could do to regain the trust and support of the front line employees.
So, just hold on. Keep your bills paid. Put cash in a safe place. When AMR collapses under the weight of the vitriol and hatred between the employees and the management, LCC, DL, and whoever else might be interested can come to the yard sale and pick up just the pieces they want. And, they can pick and choose with enough foresight to avoid unpleasant anti-trust issues. I.E., if I were LCC, I wouldn't touch AMR's DCA slots with a long stick. You know you wouldn't be allowed to keep them.
