Houston to Laredo

What the Data Says About IAH to LRD

The Houston to Laredo corridor (IAH → LRD) 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 93.5% on-time rate with an average delay of 65.4 minutes when flights run late. Over the most recent 24 months of BTS data, 617 flights were recorded on this pairing — 25 cancelled (4.1%) 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 93.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 65.4-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, Mar 2020 posted the best performance on this corridor at 96% on-time, while Feb 2020 came in at 90% on-time — a 5-point gap between best and worst recent month. For travelers evaluating the IAH to LRD route, the combination of a 93.5% on-time rate, 65.4-minute average delay, 4.1% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
