Las Vegas to San Antonio

What the Data Says About LAS to SAT

The Las Vegas to San Antonio corridor (LAS → SAT) covers roughly 1,069 miles and is served by 15 carriers, based on Bureau of Transportation Statistics reporting. Across 10,832 flights in the dataset, this route posts a 77.3% on-time rate with an average delay of 60.0 minutes when flights run late. Over the most recent 24 months of BTS data, 4,594 flights were recorded on this pairing — 27 cancelled (0.6%) and 8 diverted (0.2%). 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 10,832 total flights analyzed, the 77.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 60.0-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, Jan 2025 posted the best performance on this corridor at 90% on-time, while Jul 2024 came in at 62% on-time — a 28-point gap between best and worst recent month. For travelers evaluating the LAS to SAT route, the combination of a 77.3% on-time rate, 60.0-minute average delay, 0.6% recent cancellation rate, and 15 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
