Right now there is a HUGE training backlog, and as I see it this in the main reason the last two classes of the year were postponed.
The USPS does want us to carry more volume, but FedEx wants only a little at a time to see how it affects route structure. I would bet that Fred wants to carry all that they offer, it will just take time to get it into the system. The number of orange mail bags in conatiners on ramp is amazing.
December is predicted to put a heavy load on the system. All seats except the 727 FE were offered vacation buyback this bid month.
Last rumor I heard is still 1 or 2 classes a month starting in Feb. With the first two classes being the two from 2001. No word when and if they will open up the app window again.
Good luck
