Lake Charles to Houston

What the Data Says About LCH to IAH

The Lake Charles to Houston corridor (LCH → IAH) covers roughly 127 miles and is served by 6 carriers, based on Bureau of Transportation Statistics reporting. Across 631 flights in the dataset, this route posts a 91.8% on-time rate with an average delay of 98.7 minutes when flights run late. Over the most recent 24 months of BTS data, 631 flights were recorded on this pairing — 77 cancelled (12.2%) and 1 diverted (0.2%). 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 631 total flights analyzed, the 91.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 98.7-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 2020 posted the best performance on this corridor at 98% on-time, while Feb 2020 came in at 88% on-time — a 9-point gap between best and worst recent month. For travelers evaluating the LCH to IAH route, the combination of a 91.8% on-time rate, 98.7-minute average delay, 12.2% recent cancellation rate, and 6 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
