Charleston to New York

What the Data Says About CHS to JFK

The Charleston to New York corridor (CHS → JFK) covers roughly 636 miles and is served by 17 carriers, based on Bureau of Transportation Statistics reporting. Across 8,610 flights in the dataset, this route posts a 80% on-time rate with an average delay of 79.5 minutes when flights run late. Over the most recent 24 months of BTS data, 2,521 flights were recorded on this pairing — 84 cancelled (3.3%) and 6 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 17 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 8,610 total flights analyzed, the 80% on-time figure is statistically meaningful rather than a small-sample fluke. The 79.5-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, Nov 2024 posted the best performance on this corridor at 91% on-time, while Jul 2025 came in at 55% on-time — a 36-point gap between best and worst recent month. For travelers evaluating the CHS to JFK route, the combination of a 80% on-time rate, 79.5-minute average delay, 3.3% recent cancellation rate, and 17 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
