Kalispell to Denver

What the Data Says About FCA to DEN

The Kalispell to Denver corridor (FCA → DEN) covers roughly 752 miles and is served by 7 carriers, based on Bureau of Transportation Statistics reporting. Across 6,038 flights in the dataset, this route posts a 82% on-time rate with an average delay of 99.4 minutes when flights run late. Over the most recent 24 months of BTS data, 2,225 flights were recorded on this pairing — 18 cancelled (0.8%) and 8 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 6,038 total flights analyzed, the 82% on-time figure is statistically meaningful rather than a small-sample fluke. The 99.4-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 98% on-time, while May 2025 came in at 69% on-time — a 29-point gap between best and worst recent month. For travelers evaluating the FCA to DEN route, the combination of a 82% on-time rate, 99.4-minute average delay, 0.8% recent cancellation rate, and 7 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
