Salt Lake City to San Jose

What the Data Says About SLC to SJC

The Salt Lake City to San Jose corridor (SLC → SJC) covers roughly 584 miles and is served by 10 carriers, based on Bureau of Transportation Statistics reporting. Across 10,925 flights in the dataset, this route posts a 86.9% on-time rate with an average delay of 69.3 minutes when flights run late. Over the most recent 24 months of BTS data, 3,681 flights were recorded on this pairing — 12 cancelled (0.3%) and 3 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 10 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 10,925 total flights analyzed, the 86.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 69.3-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 92% on-time, while Jan 2024 came in at 76% on-time — a 16-point gap between best and worst recent month. For travelers evaluating the SLC to SJC route, the combination of a 86.9% on-time rate, 69.3-minute average delay, 0.3% recent cancellation rate, and 10 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
