Phoenix to Palm Springs

What the Data Says About PHX to PSP

The Phoenix to Palm Springs corridor (PHX → PSP) covers roughly 261 miles and is served by 26 carriers, based on Bureau of Transportation Statistics reporting. Across 10,033 flights in the dataset, this route posts a 83.9% on-time rate with an average delay of 68.5 minutes when flights run late. Over the most recent 24 months of BTS data, 3,231 flights were recorded on this pairing — 16 cancelled (0.5%) and 6 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 26 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 10,033 total flights analyzed, the 83.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 68.5-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, Jan 2025 posted the best performance on this corridor at 93% on-time, while Jul 2025 came in at 70% on-time — a 23-point gap between best and worst recent month. For travelers evaluating the PHX to PSP route, the combination of a 83.9% on-time rate, 68.5-minute average delay, 0.5% recent cancellation rate, and 26 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
