Kansas City to Chicago

What the Data Says About MCI to ORD

The Kansas City to Chicago corridor (MCI → ORD) covers roughly 403 miles and is served by 35 carriers, based on Bureau of Transportation Statistics reporting. Across 17,516 flights in the dataset, this route posts a 83.9% on-time rate with an average delay of 89.3 minutes when flights run late. Over the most recent 24 months of BTS data, 7,009 flights were recorded on this pairing — 116 cancelled (1.7%) and 10 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 35 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 17,516 total flights analyzed, the 83.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 89.3-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, Sep 2024 posted the best performance on this corridor at 92% on-time, while Dec 2025 came in at 66% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the MCI to ORD route, the combination of a 83.9% on-time rate, 89.3-minute average delay, 1.7% recent cancellation rate, and 35 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
