Airport Projects

Airport Master Plan

Sea-Tac’s Sustainable Airport Master Plan is a long-term blueprint for airport development to meet the needs of the traveling public, while reducing environmental and social impacts. The plan includes airfield development within the current three-runway configuration, terminal development, roadway improvements, and facility modernization and expansion possibilities.

Completion of the plan will make Sea-Tac the first large hub U.S. airport to fully incorporate sustainability as a key planning component. More info.

Baggage Handling System Optimization

In collaboration with the Transportation Security Administration (TSA), the Port of Seattle will begin construction of an optimized outbound baggage handling system (BHS) at Seattle-Tacoma International Airport. The new system will replace the aging conveyor system now in place and allow the airport to meet current and future growth.

Center Runway Reconstruction

The Center runway (designated as 16C/34C) was originally built in 1969 and was reconstructed in 2015, re-opening in December. During reconstruction, flight schedules, passenger traffic, and other operations were not disrupted. More info.

International Arrivals Facility

The Port of Seattle is working on conceptual design of an expanded International Arrivals Facility (IAF) at Seattle-Tacoma International Airport. A new IAF will advance the role the Puget Sound region plays as a leading tourist and business gateway, providing an improved passenger experience. This facility will focus resources to progress the port’s Century Agenda strategy of doubling the number of international flights and destinations over 25 years. More info.

North Satellite

The North Sea-Tac Airport Renovation is an unprecedented working arrangement between the Port of Seattle and Alaska Airlines with the goal to better serve passengers. The 40 year-old north satellite has seen only limited upgrades during its lifetime and is in need of modernization, renewal and replacement of many of its basic systems. More info.

Pre-Conditioned Air

This project provides a centralized pre-conditioned air plant, associated heating and cooling piping systems, and jet bridge terminal air handling units to serve airplanes with heating and cooling while at the gates.

Safe Corridor

To help ensure safe aircraft takeoffs and landings, the Port of Seattle will remove obstructions, primarily trees, from around Sea-Tac Airport. This effort, called the Flight Corridor Safety Program, is intended to safeguard people at the airport and in the surrounding community, and complies with Federal Aviation Administration regulations.
