San Francisco to Santa Barbara

What the Data Says About SFO to SBA

The San Francisco to Santa Barbara corridor (SFO → SBA) covers roughly 262 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 7,387 flights in the dataset, this route posts a 86% on-time rate with an average delay of 81.8 minutes when flights run late. Over the most recent 24 months of BTS data, 2,665 flights were recorded on this pairing — 44 cancelled (1.7%) and 18 diverted (0.7%). 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 7,387 total flights analyzed, the 86% on-time figure is statistically meaningful rather than a small-sample fluke. The 81.8-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, Jun 2024 posted the best performance on this corridor at 97% on-time, while Feb 2024 came in at 76% on-time — a 21-point gap between best and worst recent month. For travelers evaluating the SFO to SBA route, the combination of a 86% on-time rate, 81.8-minute average delay, 1.7% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
