Santa Ana to Denver

What the Data Says About SNA to DEN

The Santa Ana to Denver corridor (SNA → DEN) covers roughly 846 miles and is served by 9 carriers, based on Bureau of Transportation Statistics reporting. Across 20,983 flights in the dataset, this route posts a 83.5% on-time rate with an average delay of 64.4 minutes when flights run late. Over the most recent 24 months of BTS data, 7,324 flights were recorded on this pairing — 40 cancelled (0.5%) and 23 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 9 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 20,983 total flights analyzed, the 83.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 64.4-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, Oct 2024 posted the best performance on this corridor at 91% on-time, while Jul 2025 came in at 67% on-time — a 24-point gap between best and worst recent month. For travelers evaluating the SNA to DEN route, the combination of a 83.5% on-time rate, 64.4-minute average delay, 0.5% recent cancellation rate, and 9 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
