Corpus Christi to Houston

What the Data Says About CRP to IAH

The Corpus Christi to Houston corridor (CRP → IAH) covers roughly 201 miles and is served by 9 carriers, based on Bureau of Transportation Statistics reporting. Across 2,550 flights in the dataset, this route posts a 87.5% on-time rate with an average delay of 88.9 minutes when flights run late. Over the most recent 24 months of BTS data, 1,401 flights were recorded on this pairing — 25 cancelled (1.8%) and 2 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 9 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,550 total flights analyzed, the 87.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 88.9-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, May 2022 posted the best performance on this corridor at 95% on-time, while Jun 2025 came in at 71% on-time — a 24-point gap between best and worst recent month. For travelers evaluating the CRP to IAH route, the combination of a 87.5% on-time rate, 88.9-minute average delay, 1.8% recent cancellation rate, and 9 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
