Chicago to Indianapolis

What the Data Says About ORD to IND

The Chicago to Indianapolis corridor (ORD → IND) covers roughly 177 miles and is served by 41 carriers, based on Bureau of Transportation Statistics reporting. Across 20,546 flights in the dataset, this route posts a 82.2% on-time rate with an average delay of 74.2 minutes when flights run late. Over the most recent 24 months of BTS data, 8,798 flights were recorded on this pairing — 158 cancelled (1.8%) and 4 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 41 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 20,546 total flights analyzed, the 82.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 74.2-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 92% on-time, while Jul 2024 came in at 66% on-time — a 25-point gap between best and worst recent month. For travelers evaluating the ORD to IND route, the combination of a 82.2% on-time rate, 74.2-minute average delay, 1.8% recent cancellation rate, and 41 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
