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.

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.

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.

A 2009 Washington State aviation planning study assessed which existing airports could absorb overflow demand from airports projected to hit capacity limits by 2030, with Sea-Tac International among those forecast to exceed both airfield operations and passenger terminal capacity. The analysis evaluated potential alternate airports within roughly 60 miles of Sea-Tac based on factors such as available capacity, runway length, and highway access, while noting that free-market decisions by airlines and passengers would ultimately determine how traffic is distributed. The study was intended as a first-level screening, with more detailed environmental and operational analyses expected before any formal relief airport designations could be made.

During Phase III of Washington's Long-Term Air Transportation Study (2008–2009), the public was invited to weigh in on statewide aviation policies through regional meetings, electronic town halls, and an online survey. Community members raised concerns about noise, air pollution, and health impacts on neighborhoods near airports, and called for greater consideration of environmental and community needs alongside aviation capacity planning. Public feedback strongly supported investing in advanced aviation technology, while opposing demand management techniques and redistributing air traffic to nearby airports.

This document is an appendix from Washington State's 2009 Aviation System Plan, listing detailed information about airports across the state. It catalogs each airport by site number, name, city, and service level classifications under both federal (NPIAS) and state systems, covering facilities ranging from major commercial airports like Seattle's Boeing Field to small rural seaplane bases. The table includes nearly 100 airports of varying types and service levels throughout Washington State.

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 State Long-Term Air Transportation Study (LATS), authorized in 2005, is a comprehensive statewide aviation planning effort examining current airport capacity and future air transportation needs across Washington's 138 public-use airports, including Seattle-Tacoma International Airport. The study addresses key challenges such as population growth, limited funding, and land use conflicts over a 25-year planning horizon. Its findings are intended to guide long-term investment decisions and shape aviation policy at federal, state, and regional levels.
