San Francisco to San Luis Obispo

What the Data Says About SFO to SBP

The San Francisco to San Luis Obispo corridor (SFO → SBP) covers roughly 190 miles and is served by 2 carriers, based on Bureau of Transportation Statistics reporting. Across 5,726 flights in the dataset, this route posts a 82.4% on-time rate with an average delay of 93.2 minutes when flights run late. Over the most recent 24 months of BTS data, 2,115 flights were recorded on this pairing — 32 cancelled (1.5%) and 16 diverted (0.8%). Those baseline metrics tell you what to expect before you book.

Having 2 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 5,726 total flights analyzed, the 82.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 93.2-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, Jun 2024 posted the best performance on this corridor at 93% on-time, while Oct 2025 came in at 70% on-time — a 23-point gap between best and worst recent month. For travelers evaluating the SFO to SBP route, the combination of a 82.4% on-time rate, 93.2-minute average delay, 1.5% recent cancellation rate, and 2 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
