ORF to ORD questions
- What time of day is best to fly ORF to ORD?
- Before 9 AM: 84% of flights arrived on time, against 61% for departures 3 to 6 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 ORF to ORD?
- SkyWest, with a season-adjusted 78% chance of operating and arriving on time over 103 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.
- What is the worst month for delays on ORF to ORD?
- July (69% on time); the best was November (86%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
- No. These are historical odds from the US DOT on-time reports, FAA advisories and airport weather records. Check your flight status and the FAA delay board on the day you fly.
