SEA to PSP questions

- Before 9 AM: 90% of flights arrived on time, against 80% 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 SEA to PSP?
- Alaska, with a season-adjusted 84% chance of operating and arriving on time over 1,059 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.

- August (77% on time); the best was April (88%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
