Oakland to Santa Ana

What the Data Says About OAK to SNA

The Oakland to Santa Ana corridor (OAK → SNA) covers roughly 371 miles and is served by 8 carriers, based on Bureau of Transportation Statistics reporting. Across 15,066 flights in the dataset, this route posts a 85.9% on-time rate with an average delay of 49.6 minutes when flights run late. Over the most recent 24 months of BTS data, 5,230 flights were recorded on this pairing — 35 cancelled (0.7%) and 8 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 8 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 15,066 total flights analyzed, the 85.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 49.6-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, Mar 2025 posted the best performance on this corridor at 93% on-time, while Dec 2025 came in at 82% on-time — a 11-point gap between best and worst recent month. For travelers evaluating the OAK to SNA route, the combination of a 85.9% on-time rate, 49.6-minute average delay, 0.7% recent cancellation rate, and 8 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
