Fresno to San Diego

What the Data Says About FAT to SAN

The Fresno to San Diego corridor (FAT → SAN) covers roughly 314 miles and is served by 6 carriers, based on Bureau of Transportation Statistics reporting. Across 4,967 flights in the dataset, this route posts a 82.3% on-time rate with an average delay of 63.9 minutes when flights run late. Over the most recent 24 months of BTS data, 2,400 flights were recorded on this pairing — 24 cancelled (1.0%) and 14 diverted (0.6%). Those baseline metrics tell you what to expect before you book.

Having 6 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 4,967 total flights analyzed, the 82.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 63.9-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, Apr 2024 posted the best performance on this corridor at 93% on-time, while Dec 2024 came in at 52% on-time — a 42-point gap between best and worst recent month. For travelers evaluating the FAT to SAN route, the combination of a 82.3% on-time rate, 63.9-minute average delay, 1.0% recent cancellation rate, and 6 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
