Fort Myers to Chicago

What the Data Says About RSW to MDW

The Fort Myers to Chicago corridor (RSW → MDW) covers roughly 1,105 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 8,039 flights in the dataset, this route posts a 82% on-time rate with an average delay of 62.0 minutes when flights run late. Over the most recent 24 months of BTS data, 2,263 flights were recorded on this pairing — 41 cancelled (1.8%) and 8 diverted (0.4%). 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 8,039 total flights analyzed, the 82% on-time figure is statistically meaningful rather than a small-sample fluke. The 62.0-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, Sep 2025 posted the best performance on this corridor at 91% on-time, while Dec 2025 came in at 61% on-time — a 30-point gap between best and worst recent month. For travelers evaluating the RSW to MDW route, the combination of a 82% on-time rate, 62.0-minute average delay, 1.8% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
