Yes, for at least one, quite a metamorphosis has occurred.
A vacancy bid was just posted for 65 captains (but 55 captain displacements from smaller Embraer's). However, with a training completion date of about 18 months from now (no later than), that doesn't sound like the upgrade mill the salesman are forecasting. How many of the junior Embraer captaincies are backfilled will be interesting to see, but even if they all are, an 18 month window is a red flag for confidence. With at least 30 and more likely 40 new hires each and every month to build the proper bubble to support the upgrade/flow claims, they'll need to run 15/20 upgrades every MONTH and projecting an 18 month training projection which is a protection for the company doesn't seem to put much confidence in meeting the sales quotas.
BTW, the Envoy sales teams projections of the flow are based on the number of AA retirements, but I think that is error as that assumes an equal number of pilots would be needed to replace them. I've heard that AA's future "growth" once the SLI is completed and implemented along with PBS will not be increasing the number of pilots or replacing those that retire, but instead realized by increased efficiencies of the present pilots which is likely to offset to a great degree the number of AA pilots required in the future and that will be less pilots for at least a few years after the final merger synergies are implemented. That baseline is likely to be achieved late next year, which coincidentally will be when the SLI is complete, PBS is in play and the carrier can then truly realize and apply their synergies due to truly becoming one airline and also clean up the remaining 824 at Envoy.
After that, I expect no hiring at AA for perhaps up to 2-3 years as synergistic efficiencies offset the number of AA pilots that gradually retire over that period, resulting in stagnation for that same period. Another benefit for AAG will be the immediate reduction in their regional pilot losses as the flow then stops and many pilots will stay at the AAG regionals anyway and Envoy in particular because they are committed with too much invested to start over at another regional, are senior and making livable captains pay and only attrition of more junior pilots to the other two legacies or LCC's will occur giving them some breathing room.
