What the Data Says About LIT to IAH

The Little Rock to Houston corridor (LIT → IAH) covers roughly 374 miles and is served by 9 carriers, based on Bureau of Transportation Statistics reporting. Across 2,898 flights in the dataset, this route posts a 83.5% on-time rate with an average delay of 86.7 minutes when flights run late. Over the most recent 24 months of BTS data, 1,154 flights were recorded on this pairing — 22 cancelled (1.9%) and 3 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 9 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,898 total flights analyzed, the 83.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 86.7-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, Oct 2024 posted the best performance on this corridor at 97% on-time, while May 2024 came in at 63% on-time — a 33-point gap between best and worst recent month. For travelers evaluating the LIT to IAH route, the combination of a 83.5% on-time rate, 86.7-minute average delay, 1.9% recent cancellation rate, and 9 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
