This doesn't make any sense to me. The shortage is not at the bottom of the food chain (S80s), it's at the top (777s). It is not a question of finding pilots willing to upgrade. It's getting them upgraded. I know several furloughed pilots who are itching to get back, and were hoping that this might speed up their recall by a few months.
According to what I was told, the "bottleneck" is not in a shortage of bodies, it's in a shortage of training seats to put them in. How does grounding S80s solve that problem?
