Las Vegas to Austin

What the Data Says About LAS to AUS

The Las Vegas to Austin corridor (LAS → AUS) covers roughly 1,090 miles and is served by 37 carriers, based on Bureau of Transportation Statistics reporting. Across 16,765 flights in the dataset, this route posts a 77.2% on-time rate with an average delay of 65.8 minutes when flights run late. Over the most recent 24 months of BTS data, 6,287 flights were recorded on this pairing — 29 cancelled (0.5%) and 17 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 37 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 16,765 total flights analyzed, the 77.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 65.8-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, Nov 2024 posted the best performance on this corridor at 85% on-time, while Jul 2025 came in at 62% on-time — a 23-point gap between best and worst recent month. For travelers evaluating the LAS to AUS route, the combination of a 77.2% on-time rate, 65.8-minute average delay, 0.5% recent cancellation rate, and 37 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
