Casper to Denver

What the Data Says About CPR to DEN

The Casper to Denver corridor (CPR → DEN) covers roughly 230 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 7,879 flights in the dataset, this route posts a 78.4% on-time rate with an average delay of 83.7 minutes when flights run late. Over the most recent 24 months of BTS data, 3,991 flights were recorded on this pairing — 35 cancelled (0.9%) and 13 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 3 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 7,879 total flights analyzed, the 78.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 83.7-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, Nov 2025 posted the best performance on this corridor at 91% on-time, while Jun 2025 came in at 63% on-time — a 28-point gap between best and worst recent month. For travelers evaluating the CPR to DEN route, the combination of a 78.4% on-time rate, 83.7-minute average delay, 0.9% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
