Chicago to Mosinee

What the Data Says About ORD to CWA

The Chicago to Mosinee corridor (ORD → CWA) covers roughly 213 miles and is served by 5 carriers, based on Bureau of Transportation Statistics reporting. Across 2,951 flights in the dataset, this route posts a 83.3% on-time rate with an average delay of 67.9 minutes when flights run late. Over the most recent 24 months of BTS data, 1,643 flights were recorded on this pairing — 32 cancelled (1.9%) and 5 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 5 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,951 total flights analyzed, the 83.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 67.9-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, May 2023 posted the best performance on this corridor at 93% on-time, while Dec 2025 came in at 56% on-time — a 38-point gap between best and worst recent month. For travelers evaluating the ORD to CWA route, the combination of a 83.3% on-time rate, 67.9-minute average delay, 1.9% recent cancellation rate, and 5 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
