Which airline is most on time from CVG to SLC?
Delta, with a season-adjusted 83% chance of operating and arriving on time over 820 flights. The adjustment compares each airline with what the route did in the months it flew, so a carrier that skipped a stormy month gets no free credit.

July (74% on time); the best was October (93%), averaged over Jun 2023 to May 2026.
Is this a prediction for my flight?
