New York to Charlotte Amalie

What the Data Says About JFK to STT

The New York to Charlotte Amalie corridor (JFK → STT) covers roughly 1,623 miles and is served by 8 carriers, based on Bureau of Transportation Statistics reporting. Across 2,831 flights in the dataset, this route posts a 82% on-time rate with an average delay of 85.4 minutes when flights run late. Over the most recent 24 months of BTS data, 1,317 flights were recorded on this pairing — 5 cancelled (0.4%) and 5 diverted (0.4%). Those baseline metrics tell you what to expect before you book.

Having 8 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,831 total flights analyzed, the 82% on-time figure is statistically meaningful rather than a small-sample fluke. The 85.4-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 2025 posted the best performance on this corridor at 94% on-time, while Jul 2024 came in at 68% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the JFK to STT route, the combination of a 82% on-time rate, 85.4-minute average delay, 0.4% recent cancellation rate, and 8 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
