Sea-Tac Airport Comparison of Air Carrier Operations Forecasts vs. Actuals, 1975–2010
A scatter plot comparing multiple historical and projected annual air carrier operations forecasts for Seattle-Tacoma International Airport, spanning approximately 1975–2010. The chart overlays actual operations data against projections from sources including 1997 FAA and ACC (Hockaday) projections, the 1992 Flight Plan Project Final EIS, the 1996 Master Plan Update FEIS, the 1987 PSCOG Draft EIS, and several earlier studies dating back to a 1976 Sea-Tac Communities Plan, illustrating how successive forecasts consistently overestimated growth relative to actual operations. -

The Burien Airport Committee met on January 21, 2020 to discuss key aviation issues affecting the city, including advocating for a full Environmental Impact Statement (EIS) from the FAA rather than a less comprehensive Environmental Assessment (EA) related to Sea-Tac Airport's growth. The agenda also covered topics such as the Port's fuel dumping policy, updates on community re-engagement efforts through StART, and a planned trip to Washington, DC to address airplane noise concerns. Draft minutes from the December 2019 meeting reflect ongoing debates about air quality, health, and safety impacts stemming from airport expansion projects like the International and North Terminals. -
