Salt Lake City to Long Beach

What the Data Says About SLC to LGB

The Salt Lake City to Long Beach corridor (SLC → LGB) covers roughly 588 miles and is served by 16 carriers, based on Bureau of Transportation Statistics reporting. Across 8,463 flights in the dataset, this route posts a 89% on-time rate with an average delay of 63.8 minutes when flights run late. Over the most recent 24 months of BTS data, 3,158 flights were recorded on this pairing — 5 cancelled (0.2%) and 4 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 16 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 8,463 total flights analyzed, the 89% on-time figure is statistically meaningful rather than a small-sample fluke. The 63.8-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, Sep 2025 posted the best performance on this corridor at 98% on-time, while Feb 2025 came in at 82% on-time — a 15-point gap between best and worst recent month. For travelers evaluating the SLC to LGB route, the combination of a 89% on-time rate, 63.8-minute average delay, 0.2% recent cancellation rate, and 16 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
