Newark to Raleigh/Durham

What the Data Says About EWR to RDU

The Newark to Raleigh/Durham corridor (EWR → RDU) covers roughly 416 miles and is served by 21 carriers, based on Bureau of Transportation Statistics reporting. Across 13,308 flights in the dataset, this route posts a 78.4% on-time rate with an average delay of 76.0 minutes when flights run late. Over the most recent 24 months of BTS data, 4,492 flights were recorded on this pairing — 112 cancelled (2.5%) and 7 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 21 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 13,308 total flights analyzed, the 78.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 76.0-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, Feb 2024 posted the best performance on this corridor at 91% on-time, while May 2025 came in at 61% on-time — a 30-point gap between best and worst recent month. For travelers evaluating the EWR to RDU route, the combination of a 78.4% on-time rate, 76.0-minute average delay, 2.5% recent cancellation rate, and 21 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
