Hattiesburg/Laurel to Houston

What the Data Says About PIB to IAH

The Hattiesburg/Laurel to Houston corridor (PIB → IAH) covers roughly 372 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 2,609 flights in the dataset, this route posts a 86.3% on-time rate with an average delay of 138.9 minutes when flights run late. Over the most recent 24 months of BTS data, 1,083 flights were recorded on this pairing — 23 cancelled (2.1%) 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 2,609 total flights analyzed, the 86.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 138.9-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, Sep 2025 posted the best performance on this corridor at 92% on-time, while Jun 2025 came in at 65% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the PIB to IAH route, the combination of a 86.3% on-time rate, 138.9-minute average delay, 2.1% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
