Houston to Lafayette

What the Data Says About IAH to LFT

The Houston to Lafayette corridor (IAH → LFT) covers roughly 201 miles and is served by 9 carriers, based on Bureau of Transportation Statistics reporting. Across 1,612 flights in the dataset, this route posts a 85.9% on-time rate with an average delay of 98.0 minutes when flights run late. Over the most recent 24 months of BTS data, 1,612 flights were recorded on this pairing — 89 cancelled (5.5%) and 1 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 9 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,612 total flights analyzed, the 85.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 98.0-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, Apr 2020 posted the best performance on this corridor at 98% on-time, while May 2025 came in at 70% on-time — a 28-point gap between best and worst recent month. For travelers evaluating the IAH to LFT route, the combination of a 85.9% on-time rate, 98.0-minute average delay, 5.5% recent cancellation rate, and 9 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
