    Activity update & outlook: Highline Forum

    A July 2021 presentation to the Highline Forum reported that Seattle-Tacoma International Airport (SEA) was steadily recovering from pandemic-related declines, with passenger traffic reaching 71% and scheduled seat capacity reaching 83% of 2019 levels as of June 2021. By August 2021, the flight schedule had climbed to 85% of pre-pandemic capacity, with Alaska Airlines leading the recovery at 97% of its 2019 schedule, while United Airlines lagged at 66%. The document highlights that airlines had largely restored operations to meet rebounding traveler demand.

    Airport basics | Port Of Seattle

    Seattle-Tacoma International Airport handled 49.8 million passengers and 438,391 aircraft operations in 2018, ranking 8th in the U.S. by passenger volume. A noise compatibility study forecasted total annual aircraft operations to grow from approximately 301,870 in 2009 to 399,200 by 2021, driven by increases in both domestic and international air carrier activity. The airport operates three category IIIb certified runways and is dominated by Alaska Airlines, which carries over 50% of its passengers.

    Alaska Airlines letter to Port Of Seattle regarding Sustainable Airport Master Plan

    In an April 2019 letter to the Port of Seattle's Executive Director, Alaska Airlines expressed support for SeaTac airport expansion but raised serious concerns about the Sustainable Airport Master Plan (SAMP), arguing that the proposed 19-gate north terminal is disconnected from the main terminal, more gates than needed, and would leave 80% of travelers underserved. Alaska's independent consultants concluded that only 10 additional gates are necessary to meet projected 2027 passenger demand, and the airline proposed a phased 10-gate alternative as a less costly and less environmentally impactful solution. The letter urged the Port to include Alaska's alternative in the formal NEPA environmental review process to ensure a more legally defensible and balanced approach to airport development.

Issues

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.
