PHX to PHL questions

What time of day is best to fly PHX to PHL?: Before 9 AM: 92% of flights arrived on time, against 76% for departures noon to 3 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 PHX to PHL?: American, with a season-adjusted 84% chance of operating and arriving on time over 2,317 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.

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.
