ATL to LAX questions

- Before 9 AM: 87% of flights arrived on time, against 66% for departures after 9 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 ATL to LAX?
- Spirit, with a season-adjusted 82% chance of operating and arriving on time over 331 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 (68% on time); the best was October (86%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
