Fresno to Salt Lake City

What the Data Says About FAT to SLC

The Fresno to Salt Lake City corridor (FAT → SLC) covers roughly 501 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 7,043 flights in the dataset, this route posts a 92.2% on-time rate with an average delay of 103.4 minutes when flights run late. Over the most recent 24 months of BTS data, 2,331 flights were recorded on this pairing — 6 cancelled (0.3%) and 1 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 7,043 total flights analyzed, the 92.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 103.4-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, Aug 2025 posted the best performance on this corridor at 98% on-time, while Dec 2024 came in at 80% on-time — a 18-point gap between best and worst recent month. For travelers evaluating the FAT to SLC route, the combination of a 92.2% on-time rate, 103.4-minute average delay, 0.3% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
