Durango to Denver

What the Data Says About DRO to DEN

The Durango to Denver corridor (DRO → DEN) covers roughly 251 miles and is served by 7 carriers, based on Bureau of Transportation Statistics reporting. Across 9,789 flights in the dataset, this route posts a 79.6% on-time rate with an average delay of 92.3 minutes when flights run late. Over the most recent 24 months of BTS data, 3,962 flights were recorded on this pairing — 51 cancelled (1.3%) and 10 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 7 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 9,789 total flights analyzed, the 79.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 92.3-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, Oct 2024 posted the best performance on this corridor at 91% on-time, while Jul 2025 came in at 63% on-time — a 28-point gap between best and worst recent month. For travelers evaluating the DRO to DEN route, the combination of a 79.6% on-time rate, 92.3-minute average delay, 1.3% recent cancellation rate, and 7 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
