Phoenix to San Jose

What the Data Says About PHX to SJC

The Phoenix to San Jose corridor (PHX → SJC) covers roughly 621 miles and is served by 33 carriers, based on Bureau of Transportation Statistics reporting. Across 16,536 flights in the dataset, this route posts a 83.3% on-time rate with an average delay of 58.2 minutes when flights run late. Over the most recent 24 months of BTS data, 6,385 flights were recorded on this pairing — 17 cancelled (0.3%) and 5 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 33 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 16,536 total flights analyzed, the 83.3% 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, Sep 2025 posted the best performance on this corridor at 90% on-time, while Oct 2025 came in at 75% on-time — a 15-point gap between best and worst recent month. For travelers evaluating the PHX to SJC route, the combination of a 83.3% on-time rate, 58.2-minute average delay, 0.3% recent cancellation rate, and 33 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
