USAPA never would concede anything of the TA because they can't (including the arbitrated seniority list). Parker has probably learned a lot from your group's intransigence and with ALPA coming on the property again it would make the integration much easier since he sees how you guys operate. I would speculate he would appease the UAL pilots with any concerns since they will be the overwhelming majority when this plays out and it will be their union he will be dealing with once the UAL and AWA pilots vote ALPA as the bargaining agent again. You seem to believe this will take three years, but it has taken three years because our two unions messed around with fruitless negotiations, then mediation, and here we are one year after a lengthy arbitration. With UAL, the seniority list would be wrapped up in a few weeks along with applying for single carrier status which would automatically be prompted since two different unions are involved (unlike US and AWA).
By making the cuts before a merger Parker only makes it nearly impossible for the UAL pilots to buy off on his merger. All Parker has to do is wait until after the merger and then return airplanes as the leases come due, perhaps on an accelerates schedule. WIth UAL pilots running the show within one year after an integration, maybe they would allow CLT, PHX and BOS to be downsized. I do not know, it is all speculation at this point. However it seems apparent Doug Parker has learned a lot from the USEast intransigence this past three years and will be planning ahead for your group's protests to a merger. The path of least resistence is to cut the fleet after ALPA is back on the property (which, as I said, would be only a few weeks from merger consummation). Parker can wait a year, otherwise I think he knows he will not be able to sell the merger to the UAL pilots if most of them will be taking the hit- those guys have the numbers, the solidarity and the union support to capitalize on USAPA's pilots.
