Salt Lake City to Los Angeles

What the Data Says About SLC to LAX

The Salt Lake City to Los Angeles corridor (SLC → LAX) covers roughly 590 miles and is served by 44 carriers, based on Bureau of Transportation Statistics reporting. Across 27,094 flights in the dataset, this route posts a 84.2% on-time rate with an average delay of 66.7 minutes when flights run late. Over the most recent 24 months of BTS data, 8,595 flights were recorded on this pairing — 34 cancelled (0.4%) and 3 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 44 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 27,094 total flights analyzed, the 84.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 66.7-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, Nov 2025 posted the best performance on this corridor at 90% on-time, while Jul 2024 came in at 78% on-time — a 12-point gap between best and worst recent month. For travelers evaluating the SLC to LAX route, the combination of a 84.2% on-time rate, 66.7-minute average delay, 0.4% recent cancellation rate, and 44 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
