Wichita to Houston

What the Data Says About ICT to IAH

The Wichita to Houston corridor (ICT → IAH) covers roughly 542 miles and is served by 14 carriers, based on Bureau of Transportation Statistics reporting. Across 3,765 flights in the dataset, this route posts a 84% on-time rate with an average delay of 92.2 minutes when flights run late. Over the most recent 24 months of BTS data, 1,171 flights were recorded on this pairing — 19 cancelled (1.6%) and 8 diverted (0.7%). Those baseline metrics tell you what to expect before you book.

Having 14 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 3,765 total flights analyzed, the 84% on-time figure is statistically meaningful rather than a small-sample fluke. The 92.2-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, Oct 2025 posted the best performance on this corridor at 95% on-time, while Jun 2025 came in at 53% on-time — a 42-point gap between best and worst recent month. For travelers evaluating the ICT to IAH route, the combination of a 84% on-time rate, 92.2-minute average delay, 1.6% recent cancellation rate, and 14 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
