A group of legacy AA pilots have filed suit over the SLI arbitration award rendered in September of 2016.
The suit names the APA and American Airlines as defendants and alleges that the APA / American and the three member arbitration panel did not give proper weight to the superior career expectations of the plaintiffs. The suit specifically alleges that APA went to single carrier status with the US Airways pilots prior to working out a seniority arrangement that would have protected the interests of the plaintiff legacy AA pilots better.
The suit seeks a Temporary Restraining Order against AA from implementing the list, punitive damages against APA Officers and Board Members and damages against APA and American.

My $.02. The company was largely neutral on the East West dispute because it saved them money. The company as a named defendant will be very vigorous in their own defense and most likely work closely with defendant APA to have this case dismissed. The company does not want a dispute to mess up the integration and hamper their consolidation of the overall operation.
