At Seattle-Tacoma International Airport (SEA), Southwest Airlines Seattle Airport prioritizes passenger safety and efficiency, especially at security checkpoints. TSA PreCheck and CLEAR are available to speed up screening, and SEA provides a simplified security process. These services are advantageous to Southwest's customers, particularly during periods of high travel demand, when traffic at SEA's centralized and satellite checkpoints may be heavy. By enabling TSA personnel to examine luggage with extreme precision and eliminating the need for manual checks, the airport's investment in cutting-edge scanning technology, including computed tomography (CT) scanners, improves security.
