Oklahoma City to Chicago

What the Data Says About OKC to ORD

The Oklahoma City to Chicago corridor (OKC → ORD) covers roughly 693 miles and is served by 13 carriers, based on Bureau of Transportation Statistics reporting. Across 10,533 flights in the dataset, this route posts a 82.8% on-time rate with an average delay of 92.9 minutes when flights run late. Over the most recent 24 months of BTS data, 4,492 flights were recorded on this pairing — 54 cancelled (1.2%) and 12 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 13 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 10,533 total flights analyzed, the 82.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 92.9-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 91% on-time, while Jun 2025 came in at 68% on-time — a 23-point gap between best and worst recent month. For travelers evaluating the OKC to ORD route, the combination of a 82.8% on-time rate, 92.9-minute average delay, 1.2% recent cancellation rate, and 13 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
