Dallas/Fort Worth to St. George

What the Data Says About DFW to SGU

The Dallas/Fort Worth to St. George corridor (DFW → SGU) covers roughly 976 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 1,342 flights in the dataset, this route posts a 79.4% on-time rate with an average delay of 72.9 minutes when flights run late. Over the most recent 24 months of BTS data, 1,005 flights were recorded on this pairing — 5 cancelled (0.5%) and 1 diverted (0.1%). 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 1,342 total flights analyzed, the 79.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 72.9-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 90% on-time, while Jun 2025 came in at 66% on-time — a 24-point gap between best and worst recent month. For travelers evaluating the DFW to SGU route, the combination of a 79.4% on-time rate, 72.9-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.
