Las Vegas to San Diego

What the Data Says About LAS to SAN

The Las Vegas to San Diego corridor (LAS → SAN) covers roughly 258 miles and is served by 25 carriers, based on Bureau of Transportation Statistics reporting. Across 33,593 flights in the dataset, this route posts a 72.8% on-time rate with an average delay of 58.2 minutes when flights run late. Over the most recent 24 months of BTS data, 13,915 flights were recorded on this pairing — 153 cancelled (1.1%) and 16 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 25 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 33,593 total flights analyzed, the 72.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 58.2-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, Jan 2024 posted the best performance on this corridor at 83% on-time, while Jul 2024 came in at 58% on-time — a 25-point gap between best and worst recent month. For travelers evaluating the LAS to SAN route, the combination of a 72.8% on-time rate, 58.2-minute average delay, 1.1% recent cancellation rate, and 25 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
