Victoria to Houston

What the Data Says About VCT to IAH

The Victoria to Houston corridor (VCT → IAH) covers roughly 123 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 3,170 flights in the dataset, this route posts a 88% on-time rate with an average delay of 159.1 minutes when flights run late. Over the most recent 24 months of BTS data, 1,275 flights were recorded on this pairing — 38 cancelled (3.0%) and 2 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 3,170 total flights analyzed, the 88% on-time figure is statistically meaningful rather than a small-sample fluke. The 159.1-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, Apr 2024 posted the best performance on this corridor at 96% on-time, while Oct 2025 came in at 65% on-time — a 31-point gap between best and worst recent month. For travelers evaluating the VCT to IAH route, the combination of a 88% on-time rate, 159.1-minute average delay, 3.0% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
