I believe the contract will be abrogated as well, the question is what will be the limit on what AMR can get away with in terms of imposed conditions. Obviously, there are other laws governing that and the judge will be throwing out the RLA will his ruling. It's akin to a company filing bankruptcy and using it to pay its workers below minimum wage. The bankruptcy judge virtually has no limits on his power, however, it will be up to an appellate judge to determine what those limits are.
I would be getting outside council on this as well, I would not trust union attorney's, they have already bungled much of this case so far.
