Fresno to San Francisco

What the Data Says About FAT to SFO

The Fresno to San Francisco corridor (FAT → SFO) covers roughly 158 miles and is served by 2 carriers, based on Bureau of Transportation Statistics reporting. Across 6,694 flights in the dataset, this route posts a 81.2% on-time rate with an average delay of 82.1 minutes when flights run late. Over the most recent 24 months of BTS data, 2,364 flights were recorded on this pairing — 28 cancelled (1.2%) and 3 diverted (0.1%). 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 6,694 total flights analyzed, the 81.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 82.1-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, Oct 2024 posted the best performance on this corridor at 90% on-time, while Oct 2025 came in at 64% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the FAT to SFO route, the combination of a 81.2% on-time rate, 82.1-minute average delay, 1.2% recent cancellation rate, and 2 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
