Absent this merger, I would probably have retired on LOA 93 as that event falls squarely within your stated time parameters.
But no one has really seen USAPA's strategy at work, or even barely in process. The west and the company have kept USAPA in court over this contract negotiation, so I am not ready to vilify USAPA's strategy. The Ninth basically gave USAPA a green light to do their thing, and sink or swim with the results, but then the company jumped in a added another 2+ years to the process with Judge Silver's court and the Ninth again.
USAPA's strategy is clearly delineated in the rules on negotiating under the RLA and its own C&B-Ls. Sit at the table with the company, hammer something out, put it out for ratification and then let the chips fall where they may. It's a very reasonable strategy and would likely have gotten results of SOME SORT by now had not other parties seen fit to sidetrack the process.
