The interesting thing is that several of the Pacific routes have frequencies that are linked to "freight only".
If the 747F rumor is true, then mama DAL must be willing to give those frequencies up completely. They can't be sold outright because they are entangled with the passenger authorities.
I heard that as well. Also, the loads I've seen are always full so I'd be a little shocked if $40 oil doesn't shoot some life back into the freighters. We are adding an ATL flight in March which seems odd if they are almost gone.
