Fresno to Seattle

What the Data Says About FAT to SEA

The Fresno to Seattle corridor (FAT → SEA) covers roughly 748 miles and is served by 9 carriers, based on Bureau of Transportation Statistics reporting. Across 5,301 flights in the dataset, this route posts a 85.2% on-time rate with an average delay of 55.4 minutes when flights run late. Over the most recent 24 months of BTS data, 1,877 flights were recorded on this pairing — 20 cancelled (1.1%) and 4 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 9 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 5,301 total flights analyzed, the 85.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 55.4-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 2024 posted the best performance on this corridor at 93% on-time, while May 2025 came in at 69% on-time — a 24-point gap between best and worst recent month. For travelers evaluating the FAT to SEA route, the combination of a 85.2% on-time rate, 55.4-minute average delay, 1.1% recent cancellation rate, and 9 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
