Las Vegas to Salt Lake City

What the Data Says About LAS to SLC

The Las Vegas to Salt Lake City corridor (LAS → SLC) covers roughly 368 miles and is served by 18 carriers, based on Bureau of Transportation Statistics reporting. Across 22,779 flights in the dataset, this route posts a 81.8% on-time rate with an average delay of 66.0 minutes when flights run late. Over the most recent 24 months of BTS data, 8,211 flights were recorded on this pairing — 48 cancelled (0.6%) and 8 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 18 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 22,779 total flights analyzed, the 81.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 66.0-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, Nov 2024 posted the best performance on this corridor at 92% on-time, while Jul 2024 came in at 73% on-time — a 19-point gap between best and worst recent month. For travelers evaluating the LAS to SLC route, the combination of a 81.8% on-time rate, 66.0-minute average delay, 0.6% recent cancellation rate, and 18 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
