Live Estimated Checkpoint Wait Times

When to arrive at the airport

Travelers should arrive early at the airport to account for transportation, baggage and ticketing services, security screening, wayfinding and more. Seattle-Tacoma International Airport (SEA) recommends arriving at the terminal hours before your flight. Don't forget boarding starts often 45 minutes to one hour before your scheduled departure time!

Domestic Travelers International Travelers
Arrive two hours before your scheduled departure time. Arrive three hours before your scheduled departure time.

Live estimated checkpoint wait times

Estimated checkpoint wait times are available on digital signage in the terminal, below or available on the flySEA App.

  • Who is in charge of the checkpoints? Security screening operations, hours and staffing are managed by the Transportation Security Administration (TSA). Checkpoints are open daily and operational hours and lane types are determined by TSA.
     
  • How are checkpoint wait times measured? Security Checkpoint wait times are approximate and estimated by security systems and checkpoint staff.  Live checkpoint wait times for each checkpoint are published in minute increments. Wait times account for the entire screening experience from when you enter the queue to when you’ve completed screening. Live checkpoint wait times change often so make sure you still arrive to the airport early no matter what they are!
     
  • How do I pick the best checkpoint for me? If you are using a trusted traveler program make sure to use dedicated checkpoints and lanes for that product. All other travelers can use any of the general screening lanes at any checkpoint since they lead to all gates. On-site SEA Airport staff will help guide you to the best checkpoint. Even if a line looks long, if it is moving it’ll be quicker for processing.  Wait times are approximate and may vary, but they are available on digital signage throughout the terminal.
