Denver to Bozeman

What the Data Says About DEN to BZN

The Denver to Bozeman corridor (DEN → BZN) covers roughly 524 miles and is served by 17 carriers, based on Bureau of Transportation Statistics reporting. Across 14,341 flights in the dataset, this route posts a 78.4% on-time rate with an average delay of 61.6 minutes when flights run late. Over the most recent 24 months of BTS data, 5,406 flights were recorded on this pairing — 29 cancelled (0.5%) and 11 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 17 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 14,341 total flights analyzed, the 78.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 61.6-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 93% on-time, while Jan 2025 came in at 67% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the DEN to BZN route, the combination of a 78.4% on-time rate, 61.6-minute average delay, 0.5% recent cancellation rate, and 17 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
