Seattle to Wenatchee

What the Data Says About SEA to EAT

The Seattle to Wenatchee corridor (SEA → EAT) covers roughly 99 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 1,394 flights in the dataset, this route posts a 87.9% on-time rate with an average delay of 52.3 minutes when flights run late. Over the most recent 24 months of BTS data, 1,394 flights were recorded on this pairing — 36 cancelled (2.6%) and 3 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 1,394 total flights analyzed, the 87.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 52.3-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, May 2021 posted the best performance on this corridor at 100% on-time, while Jan 2022 came in at 66% on-time — a 34-point gap between best and worst recent month. For travelers evaluating the SEA to EAT route, the combination of a 87.9% on-time rate, 52.3-minute average delay, 2.6% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
