Denver to Palm Springs

What the Data Says About DEN to PSP

The Denver to Palm Springs corridor (DEN → PSP) covers roughly 776 miles and is served by 19 carriers, based on Bureau of Transportation Statistics reporting. Across 9,569 flights in the dataset, this route posts a 78.3% on-time rate with an average delay of 61.7 minutes when flights run late. Over the most recent 24 months of BTS data, 3,928 flights were recorded on this pairing — 11 cancelled (0.3%) and 16 diverted (0.4%). 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 9,569 total flights analyzed, the 78.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 61.7-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, Oct 2024 posted the best performance on this corridor at 94% on-time, while Jul 2025 came in at 66% on-time — a 28-point gap between best and worst recent month. For travelers evaluating the DEN to PSP route, the combination of a 78.3% on-time rate, 61.7-minute average delay, 0.3% recent cancellation rate, and 19 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
