Los Angeles to Salt Lake City

What the Data Says About LAX to SLC

The Los Angeles to Salt Lake City corridor (LAX → SLC) covers roughly 590 miles and is served by 45 carriers, based on Bureau of Transportation Statistics reporting. Across 27,163 flights in the dataset, this route posts a 87.1% on-time rate with an average delay of 70.3 minutes when flights run late. Over the most recent 24 months of BTS data, 8,594 flights were recorded on this pairing — 29 cancelled (0.3%) and 5 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 45 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 27,163 total flights analyzed, the 87.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 70.3-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 96% on-time, while Jul 2024 came in at 81% on-time — a 15-point gap between best and worst recent month. For travelers evaluating the LAX to SLC route, the combination of a 87.1% on-time rate, 70.3-minute average delay, 0.3% recent cancellation rate, and 45 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
