LAS to GEG questions

Before 9 AM: 93% of flights arrived on time, against 61% 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 LAS to GEG?
Southwest, with a season-adjusted 78% chance of operating and arriving on time over 750 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 (56% on time); the best was February (86%), averaged over Jun 2023 to May 2026.
Is this a prediction for my flight?
