ORD to AZO questions

What time of day is best to fly ORD to AZO?: Before 9 AM: 89% of flights arrived on time, against 67% 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 ORD to AZO?: SkyWest, with a season-adjusted 75% chance of operating and arriving on time over 38 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.
