This September 2012 Port of Seattle presentation outlines the Airport Sustainability Master Plan for Seattle-Tacoma International Airport, comparing existing and future airport layout conditions. The plan maps proposed near-term development projects across the airfield, terminal areas, parking facilities, and surrounding grounds. It serves as a long-range planning framework intended to guide responsible airport growth while reflecting the Port of Seattle's sustainability commitments.

In September 2011, the Port of Seattle briefed commissioners on an Airline Realignment Program at Seattle-Tacoma International Airport, driven by major industry mergers such as Delta-Northwest, United-Continental, and Southwest-AirTran. The program involved relocating and consolidating multiple airlines—including Alaska Air Group, American, Virgin America, and others—across different terminals and satellites, with Alaska Air Group planning to consolidate at the North Satellite and Concourse C. The total estimated cost of the realignment program ranged from $122 million to $130 million, covering capital and expense projects.
