That means they are short of pilots.
Furloughs= TDY's
I know I don't have the big picture but why are they TDYing people to DFE. Not a single DFE is getting furloughed and 4 of them are going to get displaced. DFE also seems well staffed since they dead head FOs out to LA to do trips out there. So far this month there have also been reserves available at the end of each day.
