Sioux Falls to Chicago

What the Data Says About FSD to ORD

The Sioux Falls to Chicago corridor (FSD → ORD) covers roughly 462 miles and is served by 22 carriers, based on Bureau of Transportation Statistics reporting. Across 7,573 flights in the dataset, this route posts a 80.6% on-time rate with an average delay of 94.2 minutes when flights run late. Over the most recent 24 months of BTS data, 2,865 flights were recorded on this pairing — 71 cancelled (2.5%) and 5 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 22 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 7,573 total flights analyzed, the 80.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 94.2-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, Mar 2024 posted the best performance on this corridor at 98% on-time, while Dec 2025 came in at 48% on-time — a 50-point gap between best and worst recent month. For travelers evaluating the FSD to ORD route, the combination of a 80.6% on-time rate, 94.2-minute average delay, 2.5% recent cancellation rate, and 22 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
