Marquette to Chicago

What the Data Says About MQT to ORD

The Marquette to Chicago corridor (MQT → ORD) covers roughly 303 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 2,301 flights in the dataset, this route posts a 79% on-time rate with an average delay of 97.5 minutes when flights run late. Over the most recent 24 months of BTS data, 1,165 flights were recorded on this pairing — 26 cancelled (2.2%) and 2 diverted (0.2%). 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 2,301 total flights analyzed, the 79% on-time figure is statistically meaningful rather than a small-sample fluke. The 97.5-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, Jul 2023 posted the best performance on this corridor at 87% on-time, while Oct 2025 came in at 54% on-time — a 33-point gap between best and worst recent month. For travelers evaluating the MQT to ORD route, the combination of a 79% on-time rate, 97.5-minute average delay, 2.2% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
