Figure 4-1 from a Seattle-Tacoma International Airport planning document shows historical and forecast total aircraft operations (in thousands) from 2011 to 2038, broken down by passenger airlines, all-cargo airlines, and other operations. The forecast, sourced from LeighFisher (June 2022, updated August 2023), projects growth from 429,000 operations in 2023 to 567,000 by 2038.

This table excerpt from an environmental review document compares three alternatives (No Action, Proposed Action, and Hybrid Terminal Option) for impacts on socioeconomic conditions, environmental justice populations, and children's health and safety risks at Seattle-Tacoma International Airport (SEA). Under the Proposed Action, two businesses (Doug Fox Lot and PACCAR Aviation) and one intersection (24th Avenue South from S. 150th Street) would be closed, with no significant or disproportionate adverse impacts found after mitigation.

Visible highway labels include I-5, SR-509, SR-518, SR-516, and SR-99, placing the map in the SeaTac/Burien/Des Moines area of King County, Washington.

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.
