Chicago to Flint

What the Data Says About ORD to FNT

The Chicago to Flint corridor (ORD → FNT) covers roughly 223 miles and is served by 6 carriers, based on Bureau of Transportation Statistics reporting. Across 5,638 flights in the dataset, this route posts a 77.8% on-time rate with an average delay of 79.6 minutes when flights run late. Over the most recent 24 months of BTS data, 2,400 flights were recorded on this pairing — 52 cancelled (2.2%) and 2 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 6 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 5,638 total flights analyzed, the 77.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 79.6-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, Feb 2024 posted the best performance on this corridor at 90% on-time, while Dec 2024 came in at 56% on-time — a 33-point gap between best and worst recent month. For travelers evaluating the ORD to FNT route, the combination of a 77.8% on-time rate, 79.6-minute average delay, 2.2% recent cancellation rate, and 6 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
