Getting a contract will alleviate most of the animosity. The longer the pilots wait, the smaller will be the west pilot contingent.I agree that it's an injustice and must be taken care of when possible. I see no possible reason to assume that the west contingent will be of even any slight use in this effort though, regardless of any even imagined concessions towards them, based upon all history to date.
Once the west pilots see that DOH with conditions and restrictions will make no difference to their career progression as they were, pre-nic, I believe the US pilots will be able to put this all behind them. Dragging this out, Parker risks a possible real problem with "his boys", as they are whittled down through west downsizing. From their POV, yelling "live with LOA93" at the east pilots will get awful quiet as the westies begin to take major furlough hits.
At least USAPA will provide a potentially better environment for returning westies, as opposed to ALPA.
