Airport Maps & Terminal Guide

The passenger terminal complex at Seattle/Tacoma’s SeaTac Airport is shaped like a bow, consisting of a main terminal with North & South train stations, surrounded by the Central Terminal's Concourses A, B, C & D and North & South Satellites.

Getting Around the Airport

Concourses A, B, C & D connected at post-security, enabling passengers to freely move around without having to leave the secured area. The satellites (N & S gates) are linked to the main terminal by continuously running underground loop trains. If your flight will depart from one of the satellite terminals, add an extra 10-15 minutes to your boarding schedule.

Connecting between the SEA terminals and between gates, you can take the STS train between North & South Stations. To avoid a lengthy walk from the Main Terminal to the Concourses and satellite gates, use the shuttle train:

  • The South Train Loop between the main terminal South station and the B & S Gates
  • The North Train Loop between the main terminal North station and the C and N gates;
  • The shuttle train between North & South Terminal Stations with connections to N & S Gates:
  • Getting between N gates & S gates: take the train from South or North Satellite to the Seattle Airport Main Terminal, then cross over and take the train on the opposite side, which is the shuttle that runs at post-security between the North & South stations.
  • Getting between South Satellite & Concourse C: take first the train from the South Satellite to the Main SEA Terminal, cross over to the shuttle to the North Transit Station, from there cross again to the train at the opposite side to take you to the end of Concourse C.

International Arrivals 

Passengers arrive at the South Satellite (whether changing planes or ending their trip at Sea-Tac) and then go through immigration clearance, pick up checked luggage, continue to customs (taking 30-60 minutes); thereafter procedures differ:

  • If you end your trip at SeaTac, put your luggage on the high-speed conveyor which will deliver it to the Baggage Claim. Proceed to the Main Terminal to pick up your bags at the Baggage Claim carousel 1. (Ground Transportation Information Booth is on level 3 of the parking garage.)
  • If you need to transfer to a domestic flight at Sea-Tac International, you must re-check-in your bags and go through TSA security screening prior to proceeding to your connecting flight. If you have duty-free liquid items, put them in our checked luggage to prevent confiscation at the security checkpoint.

  • Holders of the Global Entry card can reduce average wait time by 70 percent.
  • APC - Self-Service Automated Passport Control kiosks for US & Canadian citizens: These kiosks cut waiting time through customs in half.
  • MPC - Mobile passport control: Eligible passengers may submit passport information & customs declaration form to CBP (Customs) via smartphone or tablet app prior to arrival. Android & iPhone users may download the MPC app.
