This chapter from the Seattle-Tacoma International Airport Part 150 Noise Compatibility Study presents aviation activity forecasts developed to support noise exposure planning through 2018 and beyond. It covers historical passenger enplanement trends showing growth from 8.2 million in 1990 to 15.6 million in 2009, as well as domestic and international air service patterns dominated by Alaska Airlines. The forecasts, approved by the FAA in August 2010, were used to project aircraft fleet mix and noise exposure contours for future planning purposes.Open full document
