Salt Lake City to Dallas/Fort Worth

What the Data Says About SLC to DFW

The Salt Lake City to Dallas/Fort Worth corridor (SLC → DFW) covers roughly 989 miles and is served by 7 carriers, based on Bureau of Transportation Statistics reporting. Across 21,688 flights in the dataset, this route posts a 79% on-time rate with an average delay of 90.4 minutes when flights run late. Over the most recent 24 months of BTS data, 7,857 flights were recorded on this pairing — 134 cancelled (1.7%) and 44 diverted (0.6%). 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 21,688 total flights analyzed, the 79% on-time figure is statistically meaningful rather than a small-sample fluke. The 90.4-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, Feb 2024 posted the best performance on this corridor at 87% on-time, while Jan 2024 came in at 68% on-time — a 19-point gap between best and worst recent month. For travelers evaluating the SLC to DFW route, the combination of a 79% on-time rate, 90.4-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.
