Raleigh/Durham to Newark

What the Data Says About RDU to EWR

The Raleigh/Durham to Newark corridor (RDU → EWR) covers roughly 416 miles and is served by 22 carriers, based on Bureau of Transportation Statistics reporting. Across 13,304 flights in the dataset, this route posts a 76% on-time rate with an average delay of 88.1 minutes when flights run late. Over the most recent 24 months of BTS data, 4,492 flights were recorded on this pairing — 146 cancelled (3.3%) and 4 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 22 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 13,304 total flights analyzed, the 76% on-time figure is statistically meaningful rather than a small-sample fluke. The 88.1-minute average delay applies only to flights that actually ran late, so it is not the average wait across all departures — the majority of flights on this route depart on time under the BTS definition of a delay (15+ minutes past schedule).

Looking at recent months, Mar 2024 posted the best performance on this corridor at 89% on-time, while May 2025 came in at 53% on-time — a 36-point gap between best and worst recent month. For travelers evaluating the RDU to EWR route, the combination of a 76% on-time rate, 88.1-minute average delay, 3.3% recent cancellation rate, and 22 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
