I think the requirement is for there to be crews and an airplane available. Endeavor is not the only airline "saving" (Delta terminology) flying, CP and EV both save flying as well.

There is a Delta Connection report published every day on DeltaNet under "Delta Connection" which shows performance for every carrier, EVERY single delay taken across the DCI system as well as saved flights by other carriers. Search DeltaNet for it.
