What the Data Says About CGI to ORD

The Cape Girardeau to Chicago corridor (CGI → ORD) covers roughly 339 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 1,444 flights in the dataset, this route posts a 90.7% on-time rate with an average delay of 129.3 minutes when flights run late. Over the most recent 24 months of BTS data, 1,167 flights were recorded on this pairing — 57 cancelled (4.9%) and 3 diverted (0.3%). 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 1,444 total flights analyzed, the 90.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 129.3-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, Nov 2020 posted the best performance on this corridor at 98% on-time, while Jun 2021 came in at 73% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the CGI to ORD route, the combination of a 90.7% on-time rate, 129.3-minute average delay, 4.9% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
