Denver to St. George

What the Data Says About DEN to SGU

The Denver to St. George corridor (DEN → SGU) covers roughly 517 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 4,670 flights in the dataset, this route posts a 80.9% on-time rate with an average delay of 76.1 minutes when flights run late. Over the most recent 24 months of BTS data, 1,778 flights were recorded on this pairing — 9 cancelled (0.5%) and 9 diverted (0.5%). 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 4,670 total flights analyzed, the 80.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 76.1-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 2025 posted the best performance on this corridor at 95% on-time, while Aug 2024 came in at 54% on-time — a 42-point gap between best and worst recent month. For travelers evaluating the DEN to SGU route, the combination of a 80.9% on-time rate, 76.1-minute average delay, 0.5% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
