What the Data Says About PSC to SFO

The Pasco/Kennewick/Richland to San Francisco corridor (PSC → SFO) covers roughly 620 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 2,436 flights in the dataset, this route posts a 78.7% on-time rate with an average delay of 85.2 minutes when flights run late. Over the most recent 24 months of BTS data, 1,277 flights were recorded on this pairing — 5 cancelled (0.4%) and 2 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,436 total flights analyzed, the 78.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 85.2-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, Jun 2025 posted the best performance on this corridor at 95% on-time, while Dec 2023 came in at 65% on-time — a 30-point gap between best and worst recent month. For travelers evaluating the PSC to SFO route, the combination of a 78.7% on-time rate, 85.2-minute average delay, 0.4% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
