Chicago to Austin

What the Data Says About ORD to AUS

The Chicago to Austin corridor (ORD → AUS) covers roughly 977 miles and is served by 50 carriers, based on Bureau of Transportation Statistics reporting. Across 17,153 flights in the dataset, this route posts a 78% on-time rate with an average delay of 66.5 minutes when flights run late. Over the most recent 24 months of BTS data, 6,059 flights were recorded on this pairing — 57 cancelled (0.9%) and 13 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 50 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 17,153 total flights analyzed, the 78% on-time figure is statistically meaningful rather than a small-sample fluke. The 66.5-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, Oct 2024 posted the best performance on this corridor at 92% on-time, while Jan 2024 came in at 56% on-time — a 36-point gap between best and worst recent month. For travelers evaluating the ORD to AUS route, the combination of a 78% on-time rate, 66.5-minute average delay, 0.9% recent cancellation rate, and 50 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
