Pierre to Denver

What the Data Says About PIR to DEN

The Pierre to Denver corridor (PIR → DEN) covers roughly 385 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 1,380 flights in the dataset, this route posts a 85.9% on-time rate with an average delay of 122.3 minutes when flights run late. Over the most recent 24 months of BTS data, 1,269 flights were recorded on this pairing — 38 cancelled (3.0%) and 0 diverted (0.0%). 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 1,380 total flights analyzed, the 85.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 122.3-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, Apr 2020 posted the best performance on this corridor at 98% on-time, while Aug 2025 came in at 70% on-time — a 28-point gap between best and worst recent month. For travelers evaluating the PIR to DEN route, the combination of a 85.9% on-time rate, 122.3-minute average delay, 3.0% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
