San Luis Obispo to Los Angeles

What the Data Says About SBP to LAX

The San Luis Obispo to Los Angeles corridor (SBP → LAX) covers roughly 156 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 2,717 flights in the dataset, this route posts a 88.7% on-time rate with an average delay of 119.7 minutes when flights run late. Over the most recent 24 months of BTS data, 1,327 flights were recorded on this pairing — 11 cancelled (0.8%) and 0 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,717 total flights analyzed, the 88.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 119.7-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, Dec 2023 posted the best performance on this corridor at 100% on-time, while Dec 2024 came in at 70% on-time — a 30-point gap between best and worst recent month. For travelers evaluating the SBP to LAX route, the combination of a 88.7% on-time rate, 119.7-minute average delay, 0.8% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
