Palm Springs to Salt Lake City

What the Data Says About PSP to SLC

The Palm Springs to Salt Lake City corridor (PSP → SLC) covers roughly 541 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 6,002 flights in the dataset, this route posts a 93.3% on-time rate with an average delay of 126.5 minutes when flights run late. Over the most recent 24 months of BTS data, 2,029 flights were recorded on this pairing — 8 cancelled (0.4%) and 2 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 3 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 6,002 total flights analyzed, the 93.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 126.5-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, Oct 2025 posted the best performance on this corridor at 99% on-time, while Jan 2024 came in at 85% on-time — a 14-point gap between best and worst recent month. For travelers evaluating the PSP to SLC route, the combination of a 93.3% on-time rate, 126.5-minute average delay, 0.4% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
