COMMISSION AGENDA MEMORANDUM ACTION ITEM Item No. Date of Meeting DATE : December 5, 2025 TO: Stephen P. Metruck, Executive Director FROM: Darryl McKinney, Asst. Director, Aviation Security 8d January 13, 2026 SUBJECT: 2026-2027 STAC Reimbursement Memorandum Amount of this request for 2026 and 2027 not-to-exceed: $10,000,000 ACTION REQUESTED Authorization for the Executive Director to execute an agreement with the Seattle Tacoma Airline Consortium (STAC) for exit lane staffing reimbursement for two years. 2026 costs are not to exceed $4,600,000. We anticipate 2027 costs to increase by approximately 5% totaling $4,830,000. Regardless of the increase, the total two-year cost is not to exceed $10,000,000. EXECUTIVE SUMMARY Due to locally hosted special events, an increase in international flights, a projected record number of passengers, and federal budget cuts, the TSA has requested continued assistance with exit lane staffing for 2026 and 2027 at Seattle-Tacoma International Airport. The operational risks of not providing this assistance include passenger processing delays at security checkpoints and increased congestion throughout the terminal, which would also add security risk. This request allows the TSA to focus on opening all available screening lanes needed for maximum passenger throughput while STAC provides the personnel to staff exit lanes. JUSTIFICATION This contract is in the best interest of the Port, STAC, the airlines and other users of the airport, including the traveling public, to avoid congestion and delays at the security checkpoints. Diversity in Contracting Not applicable, the Port will not contract services. Template revised January 10, 2019. COMMISSION AGENDA - Action Item No. _8d_ Meeting Date: January 13, 2026 Page 2 of 3 DETAILS Scope of Work STAC agrees to provide the TSA with personnel to staff, and shall staff, the A Concourse exit lane (adjacent to checkpoint 2) and the C Concourse Exit Lane (adjacent to checkpoint 4) at the airport. The Port agrees to reimburse STAC for the cost per the terms of this agreement. Schedule Agreement shall commence on January 15, 2026 through December 31, 2027. ALTERNATIVES AND IMPLICATIONS CONSIDERED Alternative 1 - Discontinue staffing the passenger exit lanes at the airport. Ending this support could negatively impact airport operations, lead to increased security and safety concerns, and disrupt air travel causing travel delays for our customers and airlines.

Pros: (1) None for the Port Cons: (1) (2) (3) Potential Safety and Security concerns Customer Service concerns for our tenants and the traveling public Potential delays and disruption to air travel This is not the recommended alternative. Alternative 2 - Starting on January 15, 2026, begin reimbursing STAC for staffing the exit lanes at the airport utilizing approved sub-contractors according to the terms of the Memorandum of Agreement (MOU) between the Port and STAC. Cost Implications: Not to exceed $10,000,000 through December 31, 2027 Pros: (1) (2) Cons: (1) This allows the TSA to ensure appropriate staffing at the checkpoints, helping to minimize congestion.
