What the data says

The 12–3 PM departure wins.

SAN–GEG flights departing between 12–3 PM arrived on time 100% of the time, versus 81% between 6–9 PM.

Sunday scaries are real for this one.

SAN–GEG flights arrived on time 92% of the time on Tuesdays and just 74% on Sundays. That gap is worth planning around.
