Santa Rosa to Santa Ana

What the Data Says About STS to SNA

The Santa Rosa to Santa Ana corridor (STS → SNA) covers roughly 433 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 2,615 flights in the dataset, this route posts a 79.6% on-time rate with an average delay of 65.7 minutes when flights run late. Over the most recent 24 months of BTS data, 1,380 flights were recorded on this pairing — 7 cancelled (0.5%) and 1 diverted (0.1%). 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 2,615 total flights analyzed, the 79.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 65.7-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, Feb 2024 posted the best performance on this corridor at 88% on-time, while Dec 2024 came in at 62% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the STS to SNA route, the combination of a 79.6% on-time rate, 65.7-minute average delay, 0.5% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
