Chicago to Eau Claire

What the Data Says About ORD to EAU

The Chicago to Eau Claire corridor (ORD → EAU) covers roughly 269 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 2,516 flights in the dataset, this route posts a 82.2% on-time rate with an average delay of 96.7 minutes when flights run late. Over the most recent 24 months of BTS data, 1,177 flights were recorded on this pairing — 38 cancelled (3.2%) and 7 diverted (0.6%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,516 total flights analyzed, the 82.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 96.7-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, Dec 2021 posted the best performance on this corridor at 90% on-time, while Dec 2025 came in at 56% on-time — a 33-point gap between best and worst recent month. For travelers evaluating the ORD to EAU route, the combination of a 82.2% on-time rate, 96.7-minute average delay, 3.2% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
