Overview
Seattle-Tacoma International Airport (SEA), also known as Sea-Tac, is the primary international gateway for the Seattle metropolitan area. Located approximately 12 miles south of downtown Seattle in SeaTac, Washington, it serves as a major hub for both domestic and international flights. The airport has undergone continuous expansion to accommodate increasing passenger traffic, including a significant $5 billion capital program initiated in 2025 to prepare for events like the 2026 World Cup. Despite its official name, local residents often refer to it as 'Sea-Tac,' a nickname that has been a point of contention as the airport seeks to brand itself globally.
