Denver to Durango

What the Data Says About DEN to DRO

The Denver to Durango corridor (DEN → DRO) covers roughly 251 miles and is served by 7 carriers, based on Bureau of Transportation Statistics reporting. Across 9,791 flights in the dataset, this route posts a 80.2% on-time rate with an average delay of 70.8 minutes when flights run late. Over the most recent 24 months of BTS data, 3,962 flights were recorded on this pairing — 42 cancelled (1.1%) and 15 diverted (0.4%). 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 9,791 total flights analyzed, the 80.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 70.8-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 29-point gap between best and worst recent month. For travelers evaluating the DEN to DRO route, the combination of a 80.2% on-time rate, 70.8-minute average delay, 1.1% recent cancellation rate, and 7 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
