San Antonio to Las Vegas

What the Data Says About SAT to LAS

The San Antonio to Las Vegas corridor (SAT → LAS) covers roughly 1,069 miles and is served by 15 carriers, based on Bureau of Transportation Statistics reporting. Across 10,889 flights in the dataset, this route posts a 81.6% on-time rate with an average delay of 68.0 minutes when flights run late. Over the most recent 24 months of BTS data, 4,638 flights were recorded on this pairing — 32 cancelled (0.7%) and 5 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 15 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 10,889 total flights analyzed, the 81.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 68.0-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, Jul 2025 posted the best performance on this corridor at 91% on-time, while Jul 2024 came in at 63% on-time — a 28-point gap between best and worst recent month. For travelers evaluating the SAT to LAS route, the combination of a 81.6% on-time rate, 68.0-minute average delay, 0.7% recent cancellation rate, and 15 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
