- Which airline is most on time from RIC to ORD?
- United, with a season-adjusted 83% chance of operating and arriving on time over 295 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.

- December (72% on time); the best was February (88%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
