I think the big wave is really yet to come if you look at the retirements coming. This current wave is over but I think that is because so many people have come back to flying, and that is a one time thing. I didn't touch an airplane for ten years and started flying again because of the "shortage", headed to ATP-CTP in 3 weeks. There are a lot of "lost decade" people like me in the pipeline right now.
And like others have said Endeavor and Republic have no shortage; the likes of Mesa and Trans States are desperate.
