ORD to DAL questions
- What time of day is best to fly ORD to DAL?
- Before 9 AM: 93% of flights arrived on time, against 56% 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 ORD to DAL?
- Southwest, with a season-adjusted 71% chance of operating and arriving on time over 622 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 ORD to DAL?
- June (59% on time); the best was February (88%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
