Casper to Salt Lake City

What the Data Says About CPR to SLC

The Casper to Salt Lake City corridor (CPR → SLC) covers roughly 320 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 2,234 flights in the dataset, this route posts a 90.1% on-time rate with an average delay of 99.3 minutes when flights run late. Over the most recent 24 months of BTS data, 792 flights were recorded on this pairing — 4 cancelled (0.5%) 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 2,234 total flights analyzed, the 90.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 99.3-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 2022 posted the best performance on this corridor at 85% on-time, while Dec 2022 came in at 79% on-time — a 7-point gap between best and worst recent month. For travelers evaluating the CPR to SLC route, the combination of a 90.1% on-time rate, 99.3-minute average delay, 0.5% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
