ATW to ORD questions

What time of day is best to fly ATW to ORD?
Before 9 AM: 81% of flights arrived on time, against 50% 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 ATW to ORD?
Envoy, with a season-adjusted 74% chance of operating and arriving on time over 1,170 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 ATW to ORD?
January (65% on time); the best was October (78%), 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.
