Denver to Rock Springs

What the Data Says About DEN to RKS

The Denver to Rock Springs corridor (DEN → RKS) covers roughly 260 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 3,101 flights in the dataset, this route posts a 83% on-time rate with an average delay of 101.5 minutes when flights run late. Over the most recent 24 months of BTS data, 1,352 flights were recorded on this pairing — 16 cancelled (1.2%) and 10 diverted (0.7%). 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 3,101 total flights analyzed, the 83% on-time figure is statistically meaningful rather than a small-sample fluke. The 101.5-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 97% on-time, while Jul 2025 came in at 63% on-time — a 34-point gap between best and worst recent month. For travelers evaluating the DEN to RKS route, the combination of a 83% on-time rate, 101.5-minute average delay, 1.2% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
