Seattle Airport Terminal - SEATAC Terminal
All the information featured on this page was compiled and written by David Enrich, a renowned expert in aviation and airport guides since 1999.
Seattle–Tacoma International Airport, commonly known as Sea-Tac Airport (SEA), is the primary air passenger hub serving the Seattle metropolitan area in Washington State, USA. It sits between the cities of Seattle and Tacoma and is one of the busiest airports on the U.S. West Coast, connecting travelers domestically and globally with dozens of airlines.
Brief History & Origins
SEA was built by the Port of Seattle in 1944 to serve a growing aviation demand during and after World War II. The first commercial flights began in 1947, connecting regional routes that expanded rapidly as air travel grew across the United States. Over the decades, the airport evolved into a major international gateway with continuous expansions and upgrades.
Interesting Tip: The airport’s name “Sea-Tac” comes directly from its location between Seattle and Tacoma, not from any aircraft model or Hollywood connection!
Terminal & Concourse Layout
SEA has one central terminal with four main concourses (A, B, C, D) and two satellite buildings — North Satellite (N Gates) and South Satellite (S Gates) — all connected via the automated SEA Underground train system.
Terminal Highlights
- Main (Central) Terminal: Houses ticketing, check-in, TSA security, baggage claim, and most ground transportation.
- Concourses A–D: Domestic and select international departures.
- North Satellite (N Gates): Alaska Airlines hub; mostly domestic.
- South Satellite (S Gates): International flights and some domestic.
If you connect between domestic and international flights, allow extra time — walking distances can be long and the underground train, though fast, adds transit time.
Levels & Passenger Flow
- Level 1 (Arrivals / Baggage Claim): Baggage claim carousels, ride-share pickup, ground transport.
- Level 2 (Ticketing & Check-in): Check-in counters, airline desks, kiosks.
- Post-Security (Gates): Dining, retail, lounges, boarding gates.
Most food and shops are located after security — so if you want an airport meal, aim to clear security early.
Restaurants & Dining
SEA has over 50 dining options spanning local Seattle favorites, fast casual, coffee shops, and sit-down restaurants. Most are airside (after security).

Inter-terminal transportation
You can move freely between Concourses A, B, C and D since they are connected at post-security area.
Both satellites, North and South gates, are linked to the main terminal by underground loop trains, which stand for the underground people mover system.
The trip takes between 10 to 15 minutes. Opening hours: 24/7.
If you wish to connect between the terminal and the gates, the STS train is available between North and South Stations.
On the other hand, the shuttle train is really useful to avoid unnecessary walks between the main terminal, the concourses and satellite gates.
See below the inter-terminal transportation options regarding rail and shuttle train:
- South Train Loop: It follows the route between the main terminal South Station and B & S gates.
- North Train Loop: It follows the route between the main terminal North Station and C & N gates.
- The Shuttle train between North and South Terminal Stations connecting N & S gates.
