Newark to Charleston

What the Data Says About EWR to CHS

The Newark to Charleston corridor (EWR → CHS) covers roughly 628 miles and is served by 21 carriers, based on Bureau of Transportation Statistics reporting. Across 7,941 flights in the dataset, this route posts a 79.2% on-time rate with an average delay of 72.1 minutes when flights run late. Over the most recent 24 months of BTS data, 2,857 flights were recorded on this pairing — 86 cancelled (3.0%) and 5 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 7,941 total flights analyzed, the 79.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 72.1-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 90% on-time, while May 2025 came in at 62% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the EWR to CHS route, the combination of a 79.2% on-time rate, 72.1-minute average delay, 3.0% recent cancellation rate, and 21 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
