Pasco/Kennewick/Richland to Denver

What the Data Says About PSC to DEN

The Pasco/Kennewick/Richland to Denver corridor (PSC → DEN) covers roughly 852 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 4,225 flights in the dataset, this route posts a 85.6% on-time rate with an average delay of 97.7 minutes when flights run late. Over the most recent 24 months of BTS data, 1,461 flights were recorded on this pairing — 7 cancelled (0.5%) and 15 diverted (1.0%). 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 4,225 total flights analyzed, the 85.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 97.7-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 2024 posted the best performance on this corridor at 97% on-time, while Dec 2024 came in at 79% on-time — a 18-point gap between best and worst recent month. For travelers evaluating the PSC to DEN route, the combination of a 85.6% on-time rate, 97.7-minute average delay, 0.5% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
