Fresno to Denver

What the Data Says About FAT to DEN

The Fresno to Denver corridor (FAT → DEN) covers roughly 844 miles and is served by 15 carriers, based on Bureau of Transportation Statistics reporting. Across 8,392 flights in the dataset, this route posts a 85.3% on-time rate with an average delay of 82.7 minutes when flights run late. Over the most recent 24 months of BTS data, 2,898 flights were recorded on this pairing — 9 cancelled (0.3%) and 13 diverted (0.4%). Those baseline metrics tell you what to expect before you book.

Having 15 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 8,392 total flights analyzed, the 85.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 82.7-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 97% on-time, while May 2025 came in at 79% on-time — a 18-point gap between best and worst recent month. For travelers evaluating the FAT to DEN route, the combination of a 85.3% on-time rate, 82.7-minute average delay, 0.3% recent cancellation rate, and 15 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
