Charlotte Amalie to Atlanta

What the Data Says About STT to ATL

The Charlotte Amalie to Atlanta corridor (STT → ATL) covers roughly 1,599 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 4,059 flights in the dataset, this route posts a 83.8% on-time rate with an average delay of 84.6 minutes when flights run late. Over the most recent 24 months of BTS data, 1,290 flights were recorded on this pairing — 13 cancelled (1.0%) and 27 diverted (2.1%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 4,059 total flights analyzed, the 83.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 84.6-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, Jun 2025 posted the best performance on this corridor at 94% on-time, while Apr 2024 came in at 63% on-time — a 31-point gap between best and worst recent month. For travelers evaluating the STT to ATL route, the combination of a 83.8% on-time rate, 84.6-minute average delay, 1.0% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
