Los Angeles to San Antonio

What the Data Says About LAX to SAT

The Los Angeles to San Antonio corridor (LAX → SAT) covers roughly 1,211 miles and is served by 31 carriers, based on Bureau of Transportation Statistics reporting. Across 9,769 flights in the dataset, this route posts a 81.9% on-time rate with an average delay of 78.2 minutes when flights run late. Over the most recent 24 months of BTS data, 4,215 flights were recorded on this pairing — 19 cancelled (0.5%) and 6 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 31 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 9,769 total flights analyzed, the 81.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 78.2-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, Oct 2025 posted the best performance on this corridor at 92% on-time, while Mar 2024 came in at 75% on-time — a 17-point gap between best and worst recent month. For travelers evaluating the LAX to SAT route, the combination of a 81.9% on-time rate, 78.2-minute average delay, 0.5% recent cancellation rate, and 31 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
