What the Data Says About DEN to GUC

The Denver to Gunnison corridor (DEN → GUC) covers roughly 152 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 3,742 flights in the dataset, this route posts a 82.5% on-time rate with an average delay of 104.0 minutes when flights run late. Over the most recent 24 months of BTS data, 1,711 flights were recorded on this pairing — 13 cancelled (0.8%) and 8 diverted (0.5%). 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 3,742 total flights analyzed, the 82.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 104.0-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, Mar 2025 posted the best performance on this corridor at 94% on-time, while Jun 2025 came in at 73% on-time — a 21-point gap between best and worst recent month. For travelers evaluating the DEN to GUC route, the combination of a 82.5% on-time rate, 104.0-minute average delay, 0.8% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
