This is a Signatory Lease and Operating Agreement between the Port of Seattle and individual airlines for the operation of Seattle-Tacoma International Airport, covering the period 2018 to 2022. It outlines the terms under which airlines may use airport facilities including gates, terminals, airfield areas, and baggage systems, along with the associated rental rates and fees. The agreement also establishes rules for capital improvement approvals, gate assignments, and the rights and responsibilities of both the Port and signatory airlines.

Seattle-Tacoma International Airport's 2014 Competition Plan outlines how the airport manages its 79 gate positions across six concourses, with 65 gates preferentially leased by airlines and 14 controlled as common-use gates by the Port of Seattle. The plan describes policies ensuring fair access for new and existing carriers, prohibiting exclusive gate leases, and setting rates to recover costs without cross-subsidies. It also details gate monitoring procedures and expansion plans for the North Satellite terminal to accommodate growing demand from carriers such as Alaska Airlines and Delta.
