Atlanta to Charlotte Amalie

What the Data Says About ATL to STT

The Atlanta to Charlotte Amalie corridor (ATL → STT) covers roughly 1,599 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 4,063 flights in the dataset, this route posts a 82.4% on-time rate with an average delay of 50.9 minutes when flights run late. Over the most recent 24 months of BTS data, 1,290 flights were recorded on this pairing — 6 cancelled (0.5%) and 8 diverted (0.6%). 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 4,063 total flights analyzed, the 82.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 50.9-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, Jan 2024 posted the best performance on this corridor at 89% on-time, while Dec 2024 came in at 63% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the ATL to STT route, the combination of a 82.4% on-time rate, 50.9-minute average delay, 0.5% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
