Sacramento to Los Angeles

What the Data Says About SMF to LAX

The Sacramento to Los Angeles corridor (SMF → LAX) covers roughly 373 miles and is served by 20 carriers, based on Bureau of Transportation Statistics reporting. Across 27,971 flights in the dataset, this route posts a 87.8% on-time rate with an average delay of 68.5 minutes when flights run late. Over the most recent 24 months of BTS data, 10,815 flights were recorded on this pairing — 27 cancelled (0.2%) and 2 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 20 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 27,971 total flights analyzed, the 87.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 68.5-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 2024 posted the best performance on this corridor at 92% on-time, while Jul 2024 came in at 81% on-time — a 11-point gap between best and worst recent month. For travelers evaluating the SMF to LAX route, the combination of a 87.8% on-time rate, 68.5-minute average delay, 0.2% recent cancellation rate, and 20 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
