Palm Springs to Portland

What the Data Says About PSP to PDX

The Palm Springs to Portland corridor (PSP → PDX) covers roughly 873 miles and is served by 10 carriers, based on Bureau of Transportation Statistics reporting. Across 2,979 flights in the dataset, this route posts a 88.3% on-time rate with an average delay of 57.8 minutes when flights run late. Over the most recent 24 months of BTS data, 1,398 flights were recorded on this pairing — 19 cancelled (1.4%) and 1 diverted (0.1%). 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 2,979 total flights analyzed, the 88.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 57.8-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 2025 posted the best performance on this corridor at 99% on-time, while Jan 2024 came in at 79% on-time — a 20-point gap between best and worst recent month. For travelers evaluating the PSP to PDX route, the combination of a 88.3% on-time rate, 57.8-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.
