The Washington State Aviation Planning Council developed a series of policy recommendations to guide long-term decisions about the state's aviation system, covering everything from large commercial airports to small community airstrips. The policies are built on nine Guiding Principles addressing key challenges such as funding shortfalls, deferred maintenance, land use compatibility, and the need for strong partnerships among government, industry, and local communities. Decisions about airport expansion and siting are intended to be made through an open public process, balancing economic benefits with environmental and social impacts.

The Washington Aviation System Plan (2009) outlines the state's strategy for maintaining and improving its 138 public-use airports over the next 25 years, highlighting aviation's critical role in Washington's economy and transportation network. The plan was developed through the Long-Term Air Transportation Study (LATS), a three-phase process authorized in 2005, which assessed existing airport capacity and projected future needs amid challenges such as population growth, limited funding, and land use conflicts. A ten-member Aviation Planning Council was appointed to translate study findings into actionable recommendations for both commercial and general aviation across the state.

The Washington State Aviation Planning Council's 2009 Long-Term Air Transportation Study (LATS) presents recommendations to Governor Gregoire on the future of Washington's aviation system, which had shrunk from 141 to 138 public-use airports with at least two more at risk of closing. The study warns that over the next decade, 12 airports will approach or exceed capacity limits, while land use encroachment and limited resources threaten the system's viability. Public outreach showed strong support for investing in advanced technology and safety improvements, and greater efficiency in existing airports rather than building new ones.

Washington State operates 138 public-use airports, with Seattle-Tacoma International (Sea-Tac) serving as the primary commercial hub, handling approximately 15 million passengers in 2007 and ranking among the top 20 busiest airports in the nation. The state's aviation system supports over 17 million scheduled passengers and 3.7 million aircraft operations annually, contributing an estimated 171,000 jobs and $18.6 billion in sales output. General aviation is also highly active in Washington, making it the fourth busiest state in the nation for general aviation flight hours.

Washington State's aviation system serves over 17 million scheduled passengers and 600,000 tons of air cargo annually, with Seattle-Tacoma International Airport among the 20 commercial service airports statewide. The state's population and economy are projected to grow steadily through 2030, driving continued increases in aviation demand across commercial, cargo, and general aviation sectors. Economic growth in Washington is expected to outpace the national average, reinforcing the critical role airports play in jobs, commerce, and quality of life.

This chapter from Washington State's 2009 Aviation System Plan examines commercial aviation trends affecting the state's airports, set against a turbulent national backdrop. U.S. major airlines suffered $27 billion in cumulative operating losses between 2001 and 2005 due to post-9/11 demand drops, soaring fuel costs, and intense competition from low-cost carriers, before returning to profitability in 2006. In response, legacy carriers restructured costs, reduced domestic capacity, and leaned more heavily on regional airline partners, contributing to rising passenger load factors across the industry.

The Washington Aviation System Plan outlines performance objectives for public-use airports across Washington State, covering operational standards such as pavement condition, runway safety areas, and obstacle clearance. Airports are evaluated against these goals based on their classification level, ranging from Commercial Service to Seaplane Bases, with requirements tailored to each category's role and facilities. All airports, regardless of classification, are expected to maintain up-to-date planning documents and land use compatibility protections to ensure long-term safety and viability.

This 2009 Washington Aviation System Plan chapter presents long-term forecasts of passenger traffic at Washington State airports through 2030, with Sea-Tac projected to grow from roughly 14.6 million to 26.6 million enplanements—an 82% increase. Sea-Tac is expected to continue dominating statewide air travel, accounting for 85% of all passenger enplanements in 2030. The forecasts were developed to help the state and FAA identify future capacity constraints and plan necessary airport infrastructure improvements.

A 2009 Washington Aviation System Plan capacity analysis found that Sea-Tac International Airport is expected to approach or exceed 100% capacity by 2030, facing constraints in aircraft operations, passenger facilities, and aircraft storage. The study examined five types of airport capacity statewide, including airfield capacity, commercial airline passengers, air cargo, aircraft storage, and airspace, measuring existing infrastructure against both current and forecast aviation demand. Exceeding airfield capacity can lead to increased delays, higher costs for airlines and airports, and greater air and noise pollution.
