Santa Ana to Oakland

What the Data Says About SNA to OAK

The Santa Ana to Oakland corridor (SNA → OAK) covers roughly 371 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 15,102 flights in the dataset, this route posts a 84.4% on-time rate with an average delay of 52.2 minutes when flights run late. Over the most recent 24 months of BTS data, 5,225 flights were recorded on this pairing — 50 cancelled (1.0%) and 0 diverted (0.0%). 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 15,102 total flights analyzed, the 84.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 52.2-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, Nov 2024 posted the best performance on this corridor at 95% on-time, while Jun 2025 came in at 77% on-time — a 18-point gap between best and worst recent month. For travelers evaluating the SNA to OAK route, the combination of a 84.4% on-time rate, 52.2-minute average delay, 1.0% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
