The company likes what is going on now, so they are disinclined to renegotiate the TA. They would love to have some flexibility, but fear liability if they did decide to renegotiate when the time is opportune (like AA declaring bankruptcy, or Kasher awarding in favor of the east pilots.) IMHO, that's why they filed in Judge Silver's courtroom. They want to know if they can have that flexibility, or not. I don't blame them at all, and I don't see that their primary motivation is delay (as USAPA has suggested.) I disagreed with USAPA's challenge to the lawsuit because it merely delayed things even more; why not just let the judge rule one way or the other, or the third, and get it over with?
When calmer (than Judge Wake's) heads prevail, the west will realize that actually winning a DFR against a union is quite an uphill battle. Even if the resurrected Addington were again heard by Judge Wake (and even the same jury,) it would make little difference as the Ninth Circuit would have the final say.
Bring it on. Let's just get it over with.
