"Plaintiffs have made clear their desire to obtain a prompt adjudication of the merits of their claims against USAPA, so that there is no interference with the process for the US Airways/American pilots seniority integration. But, separate and apart from the West Pilots interests that will be advocated by plaintiffs, US Airways has a significant interest in its own behalf to be allowed to start and complete the seniority-integration process on a timely basis given that any interference with that process could have an adverse impact on the operational and financial benefits of the merger with American. USAPAs actions in this litigation have been, and still are, inconsistent with a prompt resolution on the merits of plaintiffs claims. Indeed, notwithstanding the Courts July 19 decision, USAPA still asserts that the West Pilots DFR claim is not ripe."
It seems USAPA is the only party seeking to delay the merger.
