The City of Burien, Des Moines, and SeaTac co-hosted a Community Open House on July 14, 2026, to present the Draft Environmental Impact Statement (DEIS) for Seattle-Tacoma International Airport's Sustainable Airport Master Plan (SAMP). The meeting covered proposed airfield, terminal, cargo, and landside expansion projects, along with their potential environmental impacts on surrounding communities. Residents were invited to learn about next steps and submit public comments on the plan.

The Commercial Aviation Coordinating Commission (CACC) held an online public engagement process in August–September 2022 to gather Washington state residents' input on potential new airport sites. Nearly 20,000 users participated, and majorities opposed all ten proposed 'greenfield' locations, citing concerns about environmental impacts, noise, farmland loss, and traffic. The most common feedback at virtual public meetings was opposition to the East King County site, with many participants also raising concerns about proximity to Sea-Tac Airport.

Snohomish County is developing a 20-year Master Plan for Paine Field Airport near Everett, WA, driven by growing aviation demand and Sea-Tac International Airport approaching its capacity limits. The plan examines existing facilities, passenger and cargo forecasts, and development alternatives, with passenger volume projected to exceed 4 million annually by 2040. Public input is being gathered through online open houses and community engagement sessions throughout the planning process.

On May 30, 2018, the Port of Seattle held its first public open house for the Sustainable Airport Master Plan (SAMP), drawing 147 attendees who discussed Sea-Tac Airport's projected growth to 56 million annual passengers and 480,000 aircraft operations by 2027. Community members raised concerns about noise, pollution, and the disproportionate impact on nearby low-income and minority communities, while Port officials explained limitations on controlling flight schedules and discussed noise mitigation efforts. The meeting notes document questions and answers covering topics such as cargo forecasts, flight pattern changes, the airport's physical footprint, and the possibility of distributing air traffic among other regional airports.
