Phoenix to Salt Lake City

What the Data Says About PHX to SLC

The Phoenix to Salt Lake City corridor (PHX → SLC) covers roughly 507 miles and is served by 38 carriers, based on Bureau of Transportation Statistics reporting. Across 30,355 flights in the dataset, this route posts a 84.5% on-time rate with an average delay of 65.0 minutes when flights run late. Over the most recent 24 months of BTS data, 11,599 flights were recorded on this pairing — 41 cancelled (0.4%) and 8 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 38 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 30,355 total flights analyzed, the 84.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 65.0-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 90% on-time, while Jul 2024 came in at 80% on-time — a 10-point gap between best and worst recent month. For travelers evaluating the PHX to SLC route, the combination of a 84.5% on-time rate, 65.0-minute average delay, 0.4% recent cancellation rate, and 38 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
