Phoenix to Sioux Falls

What the Data Says About PHX to FSD

The Phoenix to Sioux Falls corridor (PHX → FSD) covers roughly 1,081 miles and is served by 8 carriers, based on Bureau of Transportation Statistics reporting. Across 2,189 flights in the dataset, this route posts a 80.6% on-time rate with an average delay of 66.0 minutes when flights run late. Over the most recent 24 months of BTS data, 823 flights were recorded on this pairing — 2 cancelled (0.2%) and 1 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 8 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,189 total flights analyzed, the 80.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 66.0-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, Oct 2025 posted the best performance on this corridor at 84% on-time, while Dec 2025 came in at 76% on-time — a 8-point gap between best and worst recent month. For travelers evaluating the PHX to FSD route, the combination of a 80.6% on-time rate, 66.0-minute average delay, 0.2% recent cancellation rate, and 8 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
