Seattle’s N and S satellite gates rely on their train lines, while the main A–D concourses have secure-side walking links. The train line depends on the actual gate.
Where to start
Read the departure monitor and follow the train color for the appropriate satellite. Avoid an unnecessary exit toward baggage claim during a secure connection.

Routes and pickup points
Start with the direction and access area that match your trip. A public shuttle, a secure-side bus and a city coach may all appear on one airport map, but they take you to different places.

What remains to confirm
Before you use one of these routes, check the operating carrier, flight date and current stop with the airport or transport provider. These records can’t tell you whether your bag is checked through, whether you may enter the country, how long the queues are or whether you have enough time to connect.
