Port of Seattle

Seattle‑TacomaInternational Airport, commonly known as Sea‑Tac Airport, provides airfield infrastructure, passenger terminal facilities, cargo handling capabilities, and related aviation services for the Seattle‑Tacoma metropolitan area. It serves as the primary commercial airport for the region, accommodating both domestic and international flights and connecting travelers to destinations across North America, Asia, and beyond. The airport supports a range of airline operations, including major carriers that use it as a hub or focus city, and offers amenities such as retail, dining, and ground transportation options to facilitate passenger movement. Its role extends beyond passenger travel to include freight logistics, contributing to regional supply chains and economic activity. The facility operates under the oversight of the Port of Seattle, a public agency responsible for managing both maritime and aviation assets in the area.

As a division of the Port of Seattle, the airport functions as a municipal corporation rather than a privately owned entity, reflecting its public‑service mandate and accountability to local stakeholders. It is recognised as a significant gateway for trans‑pacific traffic, leveraging its geographic position to support tourism, trade, and business travel between the United States and Asia. The airport’s operational competencies include maintaining runway and taxiway systems, managing air traffic coordination in conjunction with federal authorities, and ensuring compliance with federal aviation regulations. In August 2024, the Port of Seattle and Sea‑Tac Airport reported a possible cyberattack that disrupted website and phone systems, prompting travelers to use airline applications for boarding passes and baggage tags while allowing extra time for airport processes; the Transportation Security Administration confirmed that security operations remained unaffected. This incident highlighted the airport’s reliance on digital infrastructure for customer service and underscored ongoing efforts to safeguard critical systems against cyber threats.
