At Seattle-Tacoma International Airport (SEA), security screening wait times can vary due to passenger traffic, time of travel, and checkpoint availability. To avoid delays, it’s best to arrive at least two hours early for domestic flights and three hours early for international trips. SEA Airport provides fast-track options like TSA PreCheck, CLEAR, and SEA Spot Saver to streamline security checks. Stay updated on current wait times via the flySEA App or the SEA Airport website.
