Sioux Falls to Denver

What the Data Says About FSD to DEN

The Sioux Falls to Denver corridor (FSD → DEN) covers roughly 483 miles and is served by 9 carriers, based on Bureau of Transportation Statistics reporting. Across 8,751 flights in the dataset, this route posts a 80.9% on-time rate with an average delay of 82.6 minutes when flights run late. Over the most recent 24 months of BTS data, 3,551 flights were recorded on this pairing — 39 cancelled (1.1%) and 13 diverted (0.4%). 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 8,751 total flights analyzed, the 80.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 82.6-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, Sep 2024 posted the best performance on this corridor at 89% on-time, while Jun 2025 came in at 65% on-time — a 25-point gap between best and worst recent month. For travelers evaluating the FSD to DEN route, the combination of a 80.9% on-time rate, 82.6-minute average delay, 1.1% recent cancellation rate, and 9 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
