SLC to SJC questions

Before 9 AM: 96% of flights arrived on time, against 82% 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 SLC to SJC?
SkyWest, with a season-adjusted 92% chance of operating and arriving on time over 691 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 (84% on time); the best was September (91%), averaged over Jun 2023 to May 2026.
Is this a prediction for my flight?
No. These are historical odds from the US DOT on-time reports, FAA advisories and airport weather records. Check your flight status and the FAA delay board on the day you fly.
