San Luis Obispo to Denver

What the Data Says About SBP to DEN

The San Luis Obispo to Denver corridor (SBP → DEN) covers roughly 931 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 4,285 flights in the dataset, this route posts a 85% on-time rate with an average delay of 103.8 minutes when flights run late. Over the most recent 24 months of BTS data, 1,454 flights were recorded on this pairing — 11 cancelled (0.8%) and 6 diverted (0.4%). 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 4,285 total flights analyzed, the 85% on-time figure is statistically meaningful rather than a small-sample fluke. The 103.8-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, Apr 2025 posted the best performance on this corridor at 95% on-time, while May 2025 came in at 73% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the SBP to DEN route, the combination of a 85% on-time rate, 103.8-minute average delay, 0.8% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
