Portland to Palm Springs

What the Data Says About PDX to PSP

The Portland to Palm Springs corridor (PDX → PSP) covers roughly 873 miles and is served by 10 carriers, based on Bureau of Transportation Statistics reporting. Across 2,949 flights in the dataset, this route posts a 87.2% on-time rate with an average delay of 61.3 minutes when flights run late. Over the most recent 24 months of BTS data, 1,392 flights were recorded on this pairing — 20 cancelled (1.4%) and 5 diverted (0.4%). Those baseline metrics tell you what to expect before you book.

Having 10 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,949 total flights analyzed, the 87.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 61.3-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, Jan 2025 posted the best performance on this corridor at 94% on-time, while Oct 2025 came in at 73% on-time — a 21-point gap between best and worst recent month. For travelers evaluating the PDX to PSP route, the combination of a 87.2% on-time rate, 61.3-minute average delay, 1.4% recent cancellation rate, and 10 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
