San Francisco to Las Vegas

What the Data Says About SFO to LAS

The San Francisco to Las Vegas corridor (SFO → LAS) covers roughly 414 miles and is served by 37 carriers, based on Bureau of Transportation Statistics reporting. Across 31,598 flights in the dataset, this route posts a 78.5% on-time rate with an average delay of 67.4 minutes when flights run late. Over the most recent 24 months of BTS data, 11,877 flights were recorded on this pairing — 138 cancelled (1.2%) and 7 diverted (0.1%). 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 31,598 total flights analyzed, the 78.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 67.4-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, Apr 2025 posted the best performance on this corridor at 84% on-time, while Mar 2024 came in at 54% on-time — a 30-point gap between best and worst recent month. For travelers evaluating the SFO to LAS route, the combination of a 78.5% on-time rate, 67.4-minute average delay, 1.2% recent cancellation rate, and 37 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
