SBN to ORD questions

- Before 9 AM: 73% of flights arrived on time, against 50% for departures 6 to 9 PM. Later flights inherit delays from earlier ones, so the first departures of the day usually run best.
- Which airline is most on time from SBN to ORD?
- SkyWest, with a season-adjusted 62% chance of operating and arriving on time over 2,662 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 (67% on time); the best was October (79%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
