Charlotte Amalie to Newark

What the Data Says About STT to EWR

The Charlotte Amalie to Newark corridor (STT → EWR) covers roughly 1,634 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 1,391 flights in the dataset, this route posts a 80.4% on-time rate with an average delay of 57.4 minutes when flights run late. Over the most recent 24 months of BTS data, 800 flights were recorded on this pairing — 11 cancelled (1.4%) and 23 diverted (2.9%). Those baseline metrics tell you what to expect before you book.

Having 3 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,391 total flights analyzed, the 80.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 57.4-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, Nov 2021 posted the best performance on this corridor at 73% on-time, while Dec 2021 came in at 63% on-time — a 10-point gap between best and worst recent month. For travelers evaluating the STT to EWR route, the combination of a 80.4% on-time rate, 57.4-minute average delay, 1.4% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
