The Sea-Tac Airport website offers a terminal overview map showing two terminals: the main terminal and the central terminal. The map also shows the airport's four concourses and two satellite centers that contain gates.
A visitor viewing the Sea-Tac Airport terminal overview map can click on a terminal, concourse or satellite center in the list on the left side to view a more detailed map for each area.
