LAX to SJC questions

Before 9 AM: 95% of flights arrived on time, against 78% 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 LAX to SJC?
SkyWest, with a season-adjusted 90% chance of operating and arriving on time over 2,149 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.

December (82% on time); the best was November (89%), averaged over Jun 2023 to May 2026.
Is this a prediction for my flight?
