Salt Lake City to Tucson

What the Data Says About SLC to TUS

The Salt Lake City to Tucson corridor (SLC → TUS) covers roughly 601 miles and is served by 2 carriers, based on Bureau of Transportation Statistics reporting. Across 6,604 flights in the dataset, this route posts a 90.3% on-time rate with an average delay of 62.3 minutes when flights run late. Over the most recent 24 months of BTS data, 2,171 flights were recorded on this pairing — 2 cancelled (0.1%) and 5 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 2 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 6,604 total flights analyzed, the 90.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 62.3-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, Nov 2024 posted the best performance on this corridor at 97% on-time, while Jan 2024 came in at 79% on-time — a 17-point gap between best and worst recent month. For travelers evaluating the SLC to TUS route, the combination of a 90.3% on-time rate, 62.3-minute average delay, 0.1% recent cancellation rate, and 2 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
