Denver to San Luis Obispo

What the Data Says About DEN to SBP

The Denver to San Luis Obispo corridor (DEN → SBP) covers roughly 931 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 4,263 flights in the dataset, this route posts a 77.5% on-time rate with an average delay of 73.4 minutes when flights run late. Over the most recent 24 months of BTS data, 1,457 flights were recorded on this pairing — 6 cancelled (0.4%) and 17 diverted (1.2%). 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 4,263 total flights analyzed, the 77.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 73.4-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 92% on-time, while Jun 2024 came in at 52% on-time — a 40-point gap between best and worst recent month. For travelers evaluating the DEN to SBP route, the combination of a 77.5% on-time rate, 73.4-minute average delay, 0.4% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
