Las Vegas to San Jose

What the Data Says About LAS to SJC

The Las Vegas to San Jose corridor (LAS → SJC) covers roughly 386 miles and is served by 23 carriers, based on Bureau of Transportation Statistics reporting. Across 20,933 flights in the dataset, this route posts a 79.7% on-time rate with an average delay of 56.9 minutes when flights run late. Over the most recent 24 months of BTS data, 8,894 flights were recorded on this pairing — 42 cancelled (0.5%) and 1 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 23 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 20,933 total flights analyzed, the 79.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 56.9-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 74% on-time — a 16-point gap between best and worst recent month. For travelers evaluating the LAS to SJC route, the combination of a 79.7% on-time rate, 56.9-minute average delay, 0.5% recent cancellation rate, and 23 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
