  • Sea-Tac Aircraft Operations Historical Data and Future Projections 2010–2037

    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.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
