Salt Lake City to Las Vegas

What the Data Says About SLC to LAS

The Salt Lake City to Las Vegas corridor (SLC → LAS) covers roughly 368 miles and is served by 17 carriers, based on Bureau of Transportation Statistics reporting. Across 22,829 flights in the dataset, this route posts a 78.7% on-time rate with an average delay of 68.0 minutes when flights run late. Over the most recent 24 months of BTS data, 8,191 flights were recorded on this pairing — 53 cancelled (0.6%) and 2 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 17 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 22,829 total flights analyzed, the 78.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 68.0-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 2024 posted the best performance on this corridor at 84% on-time, while Mar 2024 came in at 64% on-time — a 20-point gap between best and worst recent month. For travelers evaluating the SLC to LAS route, the combination of a 78.7% on-time rate, 68.0-minute average delay, 0.6% recent cancellation rate, and 17 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
