Upgrades in Progress at SEA Airport: Be Aware, Prepare, and Know What’s Ahead

SEATTLE – If you haven’t been to Seattle-Tacoma International Airport (SEA) for awhile, be prepared to see things you haven’t seen before. Construction is noticeable with 120 projects underway as part of Upgrade SEA, which is investing $5 billion over the next five years to create exciting opportunities now and into the future.

SEA Airport may look different, but staff are working diligently to continue the customer service we are known for, to make your travel experience the best it can be this summer. A couple of key points for travelers:

  • TSA Security Checkpoint 3 is temporarily closed for reconfiguration. This project will add two more lanes to the checkpoint, which reopens in early June, ahead of the summer season.
  • The reconfiguration of TSA Security Checkpoint 2 was recently completed, adding two lanes.

Overall, the four new lanes will add an additional 600 passengers per hour to overall throughput, helping SEA to meet peak periods of departing passengers this summer.
