Slightly less than 80% is actually better than May when 73% of DL flights were on-time (64% and 61% for UA and AA respectively). During June, DFW saw multiple strong convective storm systems move through. DL's NYC and ATL hubs also saw occasional thunderstorms. To me, 80% isn't terrible in the summertime with thunderstorms.
More on topic, I think OP saw that while Delta does move planes around, it seems they do try to minimize the overall impact to passengers.
