Charleston to Newark

What the Data Says About CHS to EWR

The Charleston to Newark corridor (CHS → EWR) covers roughly 628 miles and is served by 21 carriers, based on Bureau of Transportation Statistics reporting. Across 7,953 flights in the dataset, this route posts a 80.8% on-time rate with an average delay of 95.8 minutes when flights run late. Over the most recent 24 months of BTS data, 2,859 flights were recorded on this pairing — 80 cancelled (2.8%) and 4 diverted (0.1%). 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 7,953 total flights analyzed, the 80.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 95.8-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 94% on-time, while May 2025 came in at 59% on-time — a 36-point gap between best and worst recent month. For travelers evaluating the CHS to EWR route, the combination of a 80.8% on-time rate, 95.8-minute average delay, 2.8% recent cancellation rate, and 21 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
