Las Vegas to Houston

What the Data Says About LAS to HOU

The Las Vegas to Houston corridor (LAS → HOU) covers roughly 1,235 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 11,067 flights in the dataset, this route posts a 77% on-time rate with an average delay of 54.9 minutes when flights run late. Over the most recent 24 months of BTS data, 4,121 flights were recorded on this pairing — 29 cancelled (0.7%) and 21 diverted (0.5%). Those baseline metrics tell you what to expect before you book.

Having 4 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 11,067 total flights analyzed, the 77% on-time figure is statistically meaningful rather than a small-sample fluke. The 54.9-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, Jan 2025 posted the best performance on this corridor at 88% on-time, while Jul 2024 came in at 67% on-time — a 21-point gap between best and worst recent month. For travelers evaluating the LAS to HOU route, the combination of a 77% on-time rate, 54.9-minute average delay, 0.7% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
