What the Data Says About LBB to IAH

The Lubbock to Houston corridor (LBB → IAH) covers roughly 458 miles and is served by 5 carriers, based on Bureau of Transportation Statistics reporting. Across 1,743 flights in the dataset, this route posts a 84.6% on-time rate with an average delay of 99.9 minutes when flights run late. Over the most recent 24 months of BTS data, 1,357 flights were recorded on this pairing — 26 cancelled (1.9%) and 2 diverted (0.1%). 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 1,743 total flights analyzed, the 84.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 99.9-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, Sep 2020 posted the best performance on this corridor at 100% on-time, while Jul 2021 came in at 73% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the LBB to IAH route, the combination of a 84.6% on-time rate, 99.9-minute average delay, 1.9% recent cancellation rate, and 5 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
