Seattle-Tacoma International Airport (SEA), like the greater region, experienced unprecedented growth in the last decade. The airport is undergoing a modernization to meet current and forecast traveler demand. Improvements made will benefit the region for years. New time-saving technology and safety measures improve customer convenience and well-being. Airport infrastructure investments keep our essential supply chain stocked and maintain an economic lifeline for local businesses.
Upgrade SEA was established in 2023 and is working to elevate your experience from curb to gate. The commitment to meeting the region’s future needs with an improved level of service, reduced congestion, and less crowded terminal is top if mind, all while investing in our community and its environmental health. Upgrade SEA is modernizing SEA Airport, one capital project at a time.
