Valparaiso to Houston

What the Data Says About VPS to IAH

The Valparaiso to Houston corridor (VPS → IAH) covers roughly 528 miles and is served by 5 carriers, based on Bureau of Transportation Statistics reporting. Across 908 flights in the dataset, this route posts a 89.4% on-time rate with an average delay of 86.1 minutes when flights run late. Over the most recent 24 months of BTS data, 908 flights were recorded on this pairing — 42 cancelled (4.6%) and 1 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 5 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 908 total flights analyzed, the 89.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 86.1-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, Nov 2020 posted the best performance on this corridor at 100% on-time, while Jun 2021 came in at 73% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the VPS to IAH route, the combination of a 89.4% on-time rate, 86.1-minute average delay, 4.6% recent cancellation rate, and 5 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
