Houston to Shreveport

What the Data Says About IAH to SHV

The Houston to Shreveport corridor (IAH → SHV) covers roughly 192 miles and is served by 6 carriers, based on Bureau of Transportation Statistics reporting. Across 2,031 flights in the dataset, this route posts a 81.1% on-time rate with an average delay of 86.0 minutes when flights run late. Over the most recent 24 months of BTS data, 2,031 flights were recorded on this pairing — 74 cancelled (3.6%) and 2 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 6 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,031 total flights analyzed, the 81.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 86.0-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, Aug 2020 posted the best performance on this corridor at 96% on-time, while Jun 2025 came in at 65% on-time — a 32-point gap between best and worst recent month. For travelers evaluating the IAH to SHV route, the combination of a 81.1% on-time rate, 86.0-minute average delay, 3.6% recent cancellation rate, and 6 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
