My assessment is that they have gotten a significant percentage of pilots back with retro. In fact, one of the captains I just flew with had emailed one of our Chiefs and told him they were losing a lot of pilots with the retro shafting and Parker was making a mistake and the chief emailed him back after Kirby's flip-flop and thanked him. Apparently, many others had done the same thing. It seems many of the yes crowd want the $$$ above all else and are rationalizing any negatives as inconsequential. That will be truly sad for the junior in 2020, but AA has a long and stable history of pilots acting for self-interest with the price paid by the group in the future. This will be no different and 2020 will be no different then.
I'd advise everyone to plan accordingly for our unavoidable fire sale to Parker in 2020.
