A line chart comparing historical aircraft operations at Seattle-Tacoma International Airport from 2010–2021 with projected operations through 2037 under three scenarios: a 2022 Unconstrained Forecast, a No Action alternative, and a Proposed Action alternative. The chart shows operations peaking near 450,000 in 2019, dropping sharply in 2020 due to the COVID-19 pandemic, then recovering, with the Unconstrained Forecast reaching approximately 560,000 operations by 2037 while the Proposed Action caps near 510,000 and No Action near 475,000.Open full document
