Los Angeles to Santa Rosa

What the Data Says About LAX to STS

The Los Angeles to Santa Rosa corridor (LAX → STS) covers roughly 400 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 3,375 flights in the dataset, this route posts a 84% on-time rate with an average delay of 60.6 minutes when flights run late. Over the most recent 24 months of BTS data, 1,364 flights were recorded on this pairing — 18 cancelled (1.3%) and 15 diverted (1.1%). Those baseline metrics tell you what to expect before you book.

Having 3 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 3,375 total flights analyzed, the 84% on-time figure is statistically meaningful rather than a small-sample fluke. The 60.6-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 95% on-time, while Nov 2024 came in at 70% on-time — a 25-point gap between best and worst recent month. For travelers evaluating the LAX to STS route, the combination of a 84% on-time rate, 60.6-minute average delay, 1.3% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
