What the data says

The 6–9 AM departure wins.

LAF–ORD flights departing between 6–9 AM arrived on time 80% of the time, versus 60% between 9 AM–12 PM.

Sunday scaries are real for this one.

LAF–ORD flights arrived on time 84% of the time on Wednesdays and just 67% on Sundays. That gap is worth planning around.
