Huntsville to Chicago

What the Data Says About HSV to ORD

The Huntsville to Chicago corridor (HSV → ORD) covers roughly 510 miles and is served by 15 carriers, based on Bureau of Transportation Statistics reporting. Across 3,842 flights in the dataset, this route posts a 75.4% on-time rate with an average delay of 91.1 minutes when flights run late. Over the most recent 24 months of BTS data, 1,933 flights were recorded on this pairing — 29 cancelled (1.5%) and 3 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 15 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 3,842 total flights analyzed, the 75.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 91.1-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, May 2025 posted the best performance on this corridor at 88% on-time, while Mar 2025 came in at 55% on-time — a 33-point gap between best and worst recent month. For travelers evaluating the HSV to ORD route, the combination of a 75.4% on-time rate, 91.1-minute average delay, 1.5% recent cancellation rate, and 15 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
