Long Beach to San Jose

What the Data Says About LGB to SJC

The Long Beach to San Jose corridor (LGB → SJC) covers roughly 324 miles and is served by 2 carriers, based on Bureau of Transportation Statistics reporting. Across 6,788 flights in the dataset, this route posts a 86.7% on-time rate with an average delay of 56.2 minutes when flights run late. Over the most recent 24 months of BTS data, 2,570 flights were recorded on this pairing — 15 cancelled (0.6%) and 0 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 2 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 6,788 total flights analyzed, the 86.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 56.2-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, May 2025 posted the best performance on this corridor at 94% on-time, while Mar 2024 came in at 80% on-time — a 14-point gap between best and worst recent month. For travelers evaluating the LGB to SJC route, the combination of a 86.7% on-time rate, 56.2-minute average delay, 0.6% recent cancellation rate, and 2 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
