LAX to DTW questions

- Before 9 AM: 89% of flights arrived on time, against 76% for departures noon to 3 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 LAX to DTW?
- Delta, with a season-adjusted 83% chance of operating and arriving on time over 1,999 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.

- June (77% on time); the best was September (92%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
