4A2B isn’t permanent. Airlines hire up until the day they furlough and they furlough up until they start hiring again. There isn’t an airline in the US that has ever got the pilot manning issue right.

Some negotiated variation of 4A2B might let FedEx achieve that goal.

In the mean time, I am sitting back and waiting for the panic that is likely to happen next fall when the realize that they have outsmarted themselves.

I am more worried about the company being able to prevent me from dropping or trading trips than I am about 4A2B.
