Cheyenne to Denver

What the Data Says About CYS to DEN

The Cheyenne to Denver corridor (CYS → DEN) covers roughly 90 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 2,593 flights in the dataset, this route posts a 85.8% on-time rate with an average delay of 133.6 minutes when flights run late. Over the most recent 24 months of BTS data, 1,415 flights were recorded on this pairing — 22 cancelled (1.6%) and 1 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,593 total flights analyzed, the 85.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 133.6-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, Dec 2024 posted the best performance on this corridor at 97% on-time, while Feb 2025 came in at 61% on-time — a 36-point gap between best and worst recent month. For travelers evaluating the CYS to DEN route, the combination of a 85.8% on-time rate, 133.6-minute average delay, 1.6% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
