Salt Lake City to St. George

What the Data Says About SLC to SGU

The Salt Lake City to St. George corridor (SLC → SGU) covers roughly 272 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 8,487 flights in the dataset, this route posts a 91.2% on-time rate with an average delay of 66.8 minutes when flights run late. Over the most recent 24 months of BTS data, 2,987 flights were recorded on this pairing — 3 cancelled (0.1%) and 6 diverted (0.2%). 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 8,487 total flights analyzed, the 91.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 66.8-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, Dec 2025 posted the best performance on this corridor at 97% on-time, while Jul 2024 came in at 78% on-time — a 19-point gap between best and worst recent month. For travelers evaluating the SLC to SGU route, the combination of a 91.2% on-time rate, 66.8-minute average delay, 0.1% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
