Denver to Sacramento

What the Data Says About DEN to SMF

The Denver to Sacramento corridor (DEN → SMF) covers roughly 909 miles and is served by 15 carriers, based on Bureau of Transportation Statistics reporting. Across 21,253 flights in the dataset, this route posts a 77% on-time rate with an average delay of 61.0 minutes when flights run late. Over the most recent 24 months of BTS data, 8,013 flights were recorded on this pairing — 48 cancelled (0.6%) and 2 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 15 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 21,253 total flights analyzed, the 77% on-time figure is statistically meaningful rather than a small-sample fluke. The 61.0-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, Sep 2024 posted the best performance on this corridor at 88% on-time, while Jun 2025 came in at 60% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the DEN to SMF route, the combination of a 77% on-time rate, 61.0-minute average delay, 0.6% recent cancellation rate, and 15 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
