    Chapter 5: Aviation Trends — Washington Aviation System Plan

    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.

    Washington Aviation System Plan: Chapter 6: System Performance

    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.

    Washington Aviation System Plan, Chapter 7: Activity Forecast

    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.

    Washington Aviation System Plan: Chapter 8 — Capacity Analysis

    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.

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
