Houston to Las Vegas

What the Data Says About HOU to LAS

The Houston to Las Vegas corridor (HOU → LAS) covers roughly 1,235 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 10,900 flights in the dataset, this route posts a 80.3% on-time rate with an average delay of 58.7 minutes when flights run late. Over the most recent 24 months of BTS data, 4,101 flights were recorded on this pairing — 33 cancelled (0.8%) and 1 diverted (0.0%). 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 10,900 total flights analyzed, the 80.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 58.7-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, Dec 2025 posted the best performance on this corridor at 90% on-time, while Jul 2024 came in at 64% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the HOU to LAS route, the combination of a 80.3% on-time rate, 58.7-minute average delay, 0.8% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
