Houston to Pensacola

What the Data Says About IAH to PNS

The Houston to Pensacola corridor (IAH → PNS) covers roughly 489 miles and is served by 20 carriers, based on Bureau of Transportation Statistics reporting. Across 3,923 flights in the dataset, this route posts a 78.1% on-time rate with an average delay of 89.1 minutes when flights run late. Over the most recent 24 months of BTS data, 1,034 flights were recorded on this pairing — 19 cancelled (1.8%) and 2 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 20 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 3,923 total flights analyzed, the 78.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 89.1-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, Jan 2025 posted the best performance on this corridor at 86% on-time, while Jun 2025 came in at 58% on-time — a 28-point gap between best and worst recent month. For travelers evaluating the IAH to PNS route, the combination of a 78.1% on-time rate, 89.1-minute average delay, 1.8% recent cancellation rate, and 20 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
