Santa Ana to Sacramento

What the Data Says About SNA to SMF

The Santa Ana to Sacramento corridor (SNA → SMF) covers roughly 404 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 13,434 flights in the dataset, this route posts a 83.2% on-time rate with an average delay of 51.3 minutes when flights run late. Over the most recent 24 months of BTS data, 4,539 flights were recorded on this pairing — 30 cancelled (0.7%) and 4 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 13,434 total flights analyzed, the 83.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 51.3-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, Jan 2025 posted the best performance on this corridor at 94% on-time, while Dec 2024 came in at 79% on-time — a 15-point gap between best and worst recent month. For travelers evaluating the SNA to SMF route, the combination of a 83.2% on-time rate, 51.3-minute average delay, 0.7% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
