LAS to DTW questions

- Before 9 AM: 93% of flights arrived on time, against 72% 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 LAS to DTW?
- Frontier, with a season-adjusted 85% chance of operating and arriving on time over 56 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.

- July (73% on time); the best was November (90%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
