Palm Springs to Denver

What the Data Says About PSP to DEN

The Palm Springs to Denver corridor (PSP → DEN) covers roughly 776 miles and is served by 19 carriers, based on Bureau of Transportation Statistics reporting. Across 9,565 flights in the dataset, this route posts a 84% on-time rate with an average delay of 78.1 minutes when flights run late. Over the most recent 24 months of BTS data, 3,925 flights were recorded on this pairing — 18 cancelled (0.5%) and 11 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 19 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 9,565 total flights analyzed, the 84% on-time figure is statistically meaningful rather than a small-sample fluke. The 78.1-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, Oct 2024 posted the best performance on this corridor at 93% on-time, while May 2025 came in at 64% on-time — a 29-point gap between best and worst recent month. For travelers evaluating the PSP to DEN route, the combination of a 84% on-time rate, 78.1-minute average delay, 0.5% recent cancellation rate, and 19 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
