Houston to Lake Charles

What the Data Says About IAH to LCH

The Houston to Lake Charles corridor (IAH → LCH) covers roughly 127 miles and is served by 6 carriers, based on Bureau of Transportation Statistics reporting. Across 633 flights in the dataset, this route posts a 91.3% on-time rate with an average delay of 99.4 minutes when flights run late. Over the most recent 24 months of BTS data, 633 flights were recorded on this pairing — 79 cancelled (12.5%) and 0 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 633 total flights analyzed, the 91.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 99.4-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, Aug 2020 posted the best performance on this corridor at 98% on-time, while Feb 2020 came in at 84% on-time — a 14-point gap between best and worst recent month. For travelers evaluating the IAH to LCH route, the combination of a 91.3% on-time rate, 99.4-minute average delay, 12.5% recent cancellation rate, and 6 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
