You are definitely delusional. The UA MEC knows all about the East aspirations. They also know the pitfalls of binding arbitration. And our merger committee, MEC, and membership all consider DOH to be DOA. It is a non-starter. Slotting, relative seniority, and career expectations are all considered fair and equitable. And the "biggie," career expectations, is different in each merger. The Nicolau is considered fair in the context of your last merger. It will be similar in any merger with UA. Trust me when I say there is no love for USAPA or the "angry F/O club" at United. I believe it is you who will be in for a rude awakening.
If a pilot holds the seniority on their respective property to fly as a 757 captain, he will have a seniority number to reflects that (regardless of years of service at his respective airline of origin). If a pilot has a seniority at his respective airline to fly as a junior 737 F/O, he will have a seniority number to reflect that. If he has the seniority (juniority) to be furloughed or close to the bottom, he will have a seniority number to reflect that.
Then there will be adjustments to account for equipment types, just like Nicolau gave the top 500 or so exclusive rights to the A330 since AWA didn't have any. Obviously with 117 widebodies as opposed to your 19, the adjustment would be much larger. Longevity will obviously pay a role in things like pay and maybe even vacation and pass riding, but not in fleet or seat.
Any new flying would be shared, either equally, or proportionately based on the size of each group. Obviously there would be a no-bump/no flush provision. Also, there would probably be a certain time frame (5 years?) where pilots would be fenced into their airline's domiciles. And pay and work rules would be equal and hopefully improved for all.
Interestingly, these are exactly the same types of seniority arrangements proposed at DL/NW and between CO/UA and are mostly agreed upon as fair among the pilot groups and the MEC's (with minor adjustments here and there.) Why then are the 2700 USAPA pilots the only ones who see it differently from the other 20,000+ pilots involved in this consolidation game? This has all been debated endlessly for decades. And a US/US merger is not imminent considering that CO/UA makes much more sense. So rehashing it on this forum is senseless. The bottom line is that any dealing with USAPA will never end up in mutual agreement. It will be decided in the courts.
But do yourselves a favor and relinquish the fantasy that you will find a sympathetic ear for your cause at United. (Or AA for that matter.)
Good luck to all...
