TSA Checkpoint Construction Projects
We’re upgrading SEA and the TSA Checkpoints. The long-term renovation of the main terminal will continue to improve the facility to the with a variety of projects in the future:
- Security Screening Checkpoint 6 is temporarily unavailable and under construction to be redesigned to add space and security screening capacity to significantly improve passenger processing with the SEA Gateway project.
- Checkpoint 1 is Relocating to the south on the bag claim level. This project will create new queuing, travel document verification, and add additional security screening lanes
Types of Security Screening
Travelers can access all gates from any checkpoint. There are four checkpoints available at SEA Airport featuring general, premium, CLEAR, SEA Spot Saver, TSA PreCheck, and ADA-friendly screening. All checkpoints are ADA accessible for additional assistance please contact TSA Cares 72 hours prior to your flight.
