A line graph comparing historical aircraft operations at Sea-Tac Airport (2010–2020) against a 2022 Unconstrained Forecast, a No Action scenario, and a Proposed Action scenario through 2037. The chart shows operations dropping sharply in 2020 (likely COVID-19 impact) before recovering, with the unconstrained forecast reaching approximately 555,000 operations by 2037 versus the Proposed Action cap near 510,000.Open full document
