Seattle-Tacoma International Airport (SEA), like the greater region, experienced unprecedented growth in the last decade. We are modernizing our airport to meet current and forecast traveler demand. Improvements made will benefit our 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 is working to elevate your experience from curb to gate. We are committed to meeting our region’s future needs with an improved level of service: reduced congestion, less crowded terminals, and more efficient airfield traffic, all while investing in our community and its environmental health.
