Laredo to Houston

What the Data Says About LRD to IAH

The Laredo to Houston corridor (LRD → IAH) covers roughly 301 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 617 flights in the dataset, this route posts a 91.7% on-time rate with an average delay of 61.6 minutes when flights run late. Over the most recent 24 months of BTS data, 617 flights were recorded on this pairing — 26 cancelled (4.2%) and 1 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 3 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 617 total flights analyzed, the 91.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 61.6-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 LRD to IAH route, the combination of a 91.7% on-time rate, 61.6-minute average delay, 4.2% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
