Las Vegas to San Francisco

What the Data Says About LAS to SFO

The Las Vegas to San Francisco corridor (LAS → SFO) covers roughly 414 miles and is served by 37 carriers, based on Bureau of Transportation Statistics reporting. Across 31,552 flights in the dataset, this route posts a 74.9% on-time rate with an average delay of 63.9 minutes when flights run late. Over the most recent 24 months of BTS data, 11,870 flights were recorded on this pairing — 134 cancelled (1.1%) and 9 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 31,552 total flights analyzed, the 74.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 63.9-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 81% on-time, while Mar 2024 came in at 50% on-time — a 32-point gap between best and worst recent month. For travelers evaluating the LAS to SFO route, the combination of a 74.9% on-time rate, 63.9-minute average delay, 1.1% recent cancellation rate, and 37 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
