San Francisco to Everett

What the Data Says About SFO to PAE

The San Francisco to Everett corridor (SFO → PAE) covers roughly 710 miles and is served by 2 carriers, based on Bureau of Transportation Statistics reporting. Across 769 flights in the dataset, this route posts a 80.8% on-time rate with an average delay of 54.9 minutes when flights run late. Over the most recent 24 months of BTS data, 769 flights were recorded on this pairing — 10 cancelled (1.3%) and 2 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 2 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 769 total flights analyzed, the 80.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 54.9-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, Aug 2022 posted the best performance on this corridor at 92% on-time, while Jun 2022 came in at 71% on-time — a 21-point gap between best and worst recent month. For travelers evaluating the SFO to PAE route, the combination of a 80.8% on-time rate, 54.9-minute average delay, 1.3% recent cancellation rate, and 2 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
