San Diego to Las Vegas

What the Data Says About SAN to LAS

The San Diego to Las Vegas corridor (SAN → LAS) covers roughly 258 miles and is served by 27 carriers, based on Bureau of Transportation Statistics reporting. Across 33,400 flights in the dataset, this route posts a 77.7% on-time rate with an average delay of 68.1 minutes when flights run late. Over the most recent 24 months of BTS data, 13,857 flights were recorded on this pairing — 196 cancelled (1.4%) and 5 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 27 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 33,400 total flights analyzed, the 77.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 68.1-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 2024 posted the best performance on this corridor at 84% on-time, while Oct 2024 came in at 65% on-time — a 19-point gap between best and worst recent month. For travelers evaluating the SAN to LAS route, the combination of a 77.7% on-time rate, 68.1-minute average delay, 1.4% recent cancellation rate, and 27 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
