Portland to Fresno

What the Data Says About PDX to FAT

The Portland to Fresno corridor (PDX → FAT) covers roughly 626 miles and is served by 5 carriers, based on Bureau of Transportation Statistics reporting. Across 2,723 flights in the dataset, this route posts a 85.7% on-time rate with an average delay of 63.6 minutes when flights run late. Over the most recent 24 months of BTS data, 1,288 flights were recorded on this pairing — 1 cancelled (0.1%) and 0 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 5 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,723 total flights analyzed, the 85.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 63.6-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 91% on-time, while Dec 2024 came in at 80% on-time — a 12-point gap between best and worst recent month. For travelers evaluating the PDX to FAT route, the combination of a 85.7% on-time rate, 63.6-minute average delay, 0.1% recent cancellation rate, and 5 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
