- Which airline is most on time from MEM to ORD?
- United, with a season-adjusted 79% chance of operating and arriving on time over 332 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.

- January (70% on time); the best was October (87%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
