What I know:
Immediately after the attacks UPS and FedEx stopped all off-line jumpseats. I was able to jumpseat from Tokyo to Anchorage on a Northwest freighter on Thursday.
I talked to the Alaska Airlines folks at the terminal in Barrow. They said that they were waiting for the official paperwork to come down but they were still taking off-line jumpseats as of this evening.
Does anyone have any more info? The big questions are "For how long?" and "How can they take away something that the industry depends on?"
