Lafayette to Houston

What the Data Says About LFT to IAH

The Lafayette to Houston corridor (LFT → IAH) covers roughly 201 miles and is served by 8 carriers, based on Bureau of Transportation Statistics reporting. Across 1,586 flights in the dataset, this route posts a 87% on-time rate with an average delay of 88.4 minutes when flights run late. Over the most recent 24 months of BTS data, 1,586 flights were recorded on this pairing — 87 cancelled (5.5%) and 2 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 8 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,586 total flights analyzed, the 87% on-time figure is statistically meaningful rather than a small-sample fluke. The 88.4-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 100% on-time, while May 2025 came in at 77% on-time — a 23-point gap between best and worst recent month. For travelers evaluating the LFT to IAH route, the combination of a 87% on-time rate, 88.4-minute average delay, 5.5% recent cancellation rate, and 8 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
