How do you get between terminals at Seattle-Tacoma International Airport?
Posted on Mar 25, 2026 / Travel
Getting around SEA is pretty easy thanks to its underground train system called the Satellite Transit System. This train connects the main terminal with the North and South satellite terminals. It runs frequently, so you don’t have to wait long. Once you’re past security, you can move between concourses without leaving the secure area. Walking is also an option for some parts of the airport. Signs are clear and help guide you to your gate or connection. Just allow a bit of extra time if you have a tight connection.
