A new terminal at Seattle-Tacoma International Airport is one step closer to becoming reality.
Driving the news: The Federal Aviation Administration recently approved environmental assessments for 31 expansion projects at Sea-Tac, including the proposed 19-gate terminal, per the Port of Seattle.
The big picture: The second terminal is part of a broader master plan to ease crowding, reduce delays and modernize the airport, which ranks among the 15 busiest in the U.S.
52 million passengers came through Sea-Tac last year, and 56 million are forecast to pass through annually by 2032.
Zoom in: Planned improvements include automated people movers connecting the new terminal with the main one; a new rental car facility; and airfield and fuel-system upgrades.
What's next: The Port of Seattle plans to complete a state-level environmental review of the projects by the end of 2026.
