What the Data Says About SHV to IAH

The Shreveport to Houston corridor (SHV → IAH) covers roughly 192 miles and is served by 6 carriers, based on Bureau of Transportation Statistics reporting. Across 2,029 flights in the dataset, this route posts a 80.6% on-time rate with an average delay of 88.8 minutes when flights run late. Over the most recent 24 months of BTS data, 2,029 flights were recorded on this pairing — 74 cancelled (3.6%) and 1 diverted (0.0%). 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 2,029 total flights analyzed, the 80.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 88.8-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, Sep 2020 posted the best performance on this corridor at 94% on-time, while Aug 2021 came in at 69% on-time — a 25-point gap between best and worst recent month. For travelers evaluating the SHV to IAH route, the combination of a 80.6% on-time rate, 88.8-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.
