This explainer from Sea-Tac Noise.Info describes Seattle-Tacoma International Airport as a large-scale assembly line with three interconnected sections: air (airspace and runways), terminal (gates, passengers, and baggage), and road (cars, trucks, pedestrians, and light rail). The airport processes people, cargo, and vehicles across roughly 450,000 flights per year—more than 1,230 per day—with the goal of moving everything smoothly between sections and no delays. A bottleneck in any one section can ripple through the entire system, making capacity planning central to the airport's Sustainable Airport Master Plan (SAMP).

A presentation slide titled 'Environmental review analysis based on constrained growth scenarios' shows a line chart comparing historical operations data (2011–2020), a 2022 unconstrained forecast, and two constrained growth scenarios—No Action and Proposed Action—projected through 2037. The Proposed Action constrained scenario reaches approximately 515,000 operations by 2037, while the No Action constrained scenario plateaus near 480,000, both falling well below the unconstrained 2022 forecast of approximately 560,000.
