RDU to EWR questions

What time of day is best to fly RDU to EWR?: Before 9 AM: 91% of flights arrived on time, against 55% for departures 6 to 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 RDU to EWR?: United, with a season-adjusted 74% chance of operating and arriving on time over 1,507 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.
What is the worst month for delays on RDU to EWR?: July (62% on time); the best was February (84%), averaged over Jun 2023 to May 2026.
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.
