American Airlines I'm sure still has plenty of applications on file. AA finding pilots for mainline won't be a problem anytime soon. Training might get backlogged a bit, but that is minor in the long term.
The problem AA WILL have is finding pilots in the long term for their regionals. Just as we told them in bankruptcy, they have needed to throw money and the promise of flow at pilots to get them in the door.
AAG will have a decision to make. When the supply of new hires slows applying to AAG regionals, they will either need to increase contractual flow to lower the flow time, or make the regionals the only way to get to AA eventually, (or both) if they want to keep the regionals operating. With its CS series order, to some extent Delta has already signaled they believe the regionals will shrink.
Until apps at the WO's starts to drop off, nothing will change.
