What the Data Says About DEN to ATY

The Denver to Watertown corridor (DEN → ATY) covers roughly 519 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 763 flights in the dataset, this route posts a 88.5% on-time rate with an average delay of 76.9 minutes when flights run late. Over the most recent 24 months of BTS data, 732 flights were recorded on this pairing — 10 cancelled (1.4%) and 2 diverted (0.3%). 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 763 total flights analyzed, the 88.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 76.9-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).

For travelers evaluating the DEN to ATY route, the combination of a 88.5% on-time rate, 76.9-minute average delay, 1.4% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
