Charlotte Amalie to New York

What the Data Says About STT to JFK

The Charlotte Amalie to New York corridor (STT → JFK) covers roughly 1,623 miles and is served by 8 carriers, based on Bureau of Transportation Statistics reporting. Across 2,727 flights in the dataset, this route posts a 79.6% on-time rate with an average delay of 91.5 minutes when flights run late. Over the most recent 24 months of BTS data, 1,317 flights were recorded on this pairing — 12 cancelled (0.9%) and 20 diverted (1.5%). 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 2,727 total flights analyzed, the 79.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 91.5-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, May 2025 posted the best performance on this corridor at 92% on-time, while Jul 2024 came in at 53% on-time — a 39-point gap between best and worst recent month. For travelers evaluating the STT to JFK route, the combination of a 79.6% on-time rate, 91.5-minute average delay, 0.9% recent cancellation rate, and 8 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
