Dallas/Fort Worth to Salt Lake City

What the Data Says About DFW to SLC

The Dallas/Fort Worth to Salt Lake City corridor (DFW → SLC) covers roughly 989 miles and is served by 7 carriers, based on Bureau of Transportation Statistics reporting. Across 21,693 flights in the dataset, this route posts a 76.2% on-time rate with an average delay of 78.7 minutes when flights run late. Over the most recent 24 months of BTS data, 7,860 flights were recorded on this pairing — 131 cancelled (1.7%) and 9 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 7 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 21,693 total flights analyzed, the 76.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 78.7-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, Feb 2024 posted the best performance on this corridor at 86% on-time, while Aug 2025 came in at 56% on-time — a 30-point gap between best and worst recent month. For travelers evaluating the DFW to SLC route, the combination of a 76.2% on-time rate, 78.7-minute average delay, 1.7% recent cancellation rate, and 7 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
