Sea-Tac International Airport’s Gateway Project officially wraps up Wednesday after two years of construction and more than $500 million in investment, transforming the decades-old terminal ahead of summer travel and the FIFA World Cup.
Both Alaska Airlines and the Port of Seattle call it a one-of-a-kind project. The remodeling and expansion updated the terminal to reflect growth in travel through the airport. The project’s completion comes in time for the typical summer travel rush and the World Cup in June.
Alaska Airlines said the construction project is the largest they have ever overseen, and new flights are coming this spring. Port of Seattle Commission President Ryan Calkins said that each year, an average of 52 million people pass through Sea-Tac.
“The demand for travel to and through SEA continues to grow each year,” said Calkins. “The lighter, brighter, and more welcoming space is representative of our region and the directions we’re going as a global gateway.”
For travelers who have navigated construction barriers and detours over the past two years, the changes will be immediately visible. The terminal modernization addresses capacity constraints that made peak travel times congested and difficult to navigate. With the World Cup bringing international visitors to Seattle in June, the timing allows the airport to showcase its upgraded facilities.
Sea-Tac has grown into one of the fastest-growing airports in the country, driven by the region’s tech economy and Seattle’s position as a gateway to Asia. The Gateway Project represents one piece of broader infrastructure improvements the airport needs to handle increasing passenger volumes.
