Houston to Lubbock

What the Data Says About IAH to LBB

The Houston to Lubbock corridor (IAH → LBB) covers roughly 458 miles and is served by 5 carriers, based on Bureau of Transportation Statistics reporting. Across 1,744 flights in the dataset, this route posts a 84.6% on-time rate with an average delay of 86.4 minutes when flights run late. Over the most recent 24 months of BTS data, 1,357 flights were recorded on this pairing — 21 cancelled (1.5%) and 7 diverted (0.5%). Those baseline metrics tell you what to expect before you book.

Having 5 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,744 total flights analyzed, the 84.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 86.4-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 97% on-time, while May 2021 came in at 74% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the IAH to LBB route, the combination of a 84.6% on-time rate, 86.4-minute average delay, 1.5% recent cancellation rate, and 5 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
