Denver to Casper

What the Data Says About DEN to CPR

The Denver to Casper corridor (DEN → CPR) covers roughly 230 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 7,882 flights in the dataset, this route posts a 79.3% on-time rate with an average delay of 77.9 minutes when flights run late. Over the most recent 24 months of BTS data, 3,992 flights were recorded on this pairing — 40 cancelled (1.0%) and 8 diverted (0.2%). 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 7,882 total flights analyzed, the 79.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 77.9-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, Dec 2023 posted the best performance on this corridor at 92% on-time, while Jun 2025 came in at 63% on-time — a 29-point gap between best and worst recent month. For travelers evaluating the DEN to CPR route, the combination of a 79.3% on-time rate, 77.9-minute average delay, 1.0% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
