Yep. I believe UAL did something similar though. Not sure about NW/AA/CA/US/etc.

Also DL furloughs accrued longevity while on furlough which was a very rare thing at the time. Most pilots at other airlines didn't. That may have been copied in post BK contracts by most legacies by now though I think. So if you got furloughed on year one you returned to year 5 (or whatever it was) pay etc. Thats was huge for many.
