2023-09-01Appendix B Aircraft and Activity Forecast
This technical memorandum, prepared by Leigh Fisher for the Port of Seattle in September 2023, provides an updated aviation activity forecast for Seattle-Tacoma International Airport as part of a FAA Part 150 noise study. It outlines forecast and operational assumptions—including projected aircraft types and flight activity levels—that were used to model future noise conditions around Sea-Tac. The report is accompanied by operational data appendices supporting the airport's long-term noise compatibility planning efforts. -
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. -
2022-09-12Snohomish County Airport/Paine Field master plan update
This document is the Master Plan Update for Snohomish County Airport/Paine Field, covering a comprehensive range of planning topics including existing airport conditions, aviation activity forecasts, capacity analysis, facility requirements, and a long-term development program. It outlines airfield and landside infrastructure needs, environmental considerations, and financial planning strategies for the airport's future growth. Note that this plan pertains to Paine Field in Snohomish County and does not directly address noise policy at Seattle-Tacoma International Airport. -
SAMP-2015-0519-BP12-PortofSeattle Page 05
Slide 5 from Seattle-Tacoma International Airport's Sustainable Airport Master Plan (SAMP) presenting an unconstrained activity forecast projecting growth to 66 million annual passengers and 540,000 annual operations over 20 years. Includes a comparison table of 2013 PAX rankings, developed acreage, and PAX-per-acre ratios for Sea-Tac, San Francisco, Newark, Boston, and Las Vegas airports. -
2022-07-10Part 4: Trends and Forecasts — Chapter 4.1, Central Puget Sound Region Population
This document is Part 4 of a Master Plan study for Sea-Tac International Airport, focusing on trends and forecasts for the Central Puget Sound Region. It examines population and economic growth data to project future air traffic demand, noting that the four-county area around Seattle held over 1.9 million people in 1970—56% of Washington State's population. While the region grew rapidly through the 1950s and 1960s, the plan anticipates more modest growth in the 1970s relative to national averages. -
Tableau Historic Operations 2005-2020
A data table sourced from the Federal Aviation Administration (FAA) showing historic aircraft operations from 2005 to 2020, broken down by Air Carrier, Air Taxi, General Aviation, and Military/Training categories, along with total operations and percent change from prior year. The table shows a sharp -34.3% decline in total operations in 2020, dropping to 296,048, compared to 450,487 in 2019. -
Tableau Historic Passenger Levels 2005-2020
A Port of Seattle Business Intelligence dashboard showing Sea-Tac Airport's historic air passenger levels from 2005 to 2020, broken down by domestic and international deplaned/enplaned totals. The report highlights a 61.3% decline in total passengers in 2020 (20,045,348) compared to a peak of 51,829,239 in 2019, reflecting the COVID-19 pandemic's impact on air travel. -
2022-03-18Tableau Operations Carrier vs. Taxi
A line chart showing scheduled aircraft operations over time for three categories: Air Carrier (aircraft with over 70 seats), Air Taxi (aircraft with less than 70 seats), and All Other. Air Carrier operations peak near 450K before declining sharply at the right end of the chart, while Air Taxi operations rise and then fall dramatically to near zero.
