Main Terminal / Concourses at Seattle Tacoma SEA Airport

The passenger terminal complex at Seattle/Tacoma’s Sea-Tac Airport is shaped like a bow, consisting of a main terminal with North & South train stations, surrounded by the Central Terminal with access to ConcoursesThe Main Terminal's North & South Stations are to the right & left of the complex, connecting both ends by train.  The South Satellite (S gates) serves all international arrivals (except those with U.S. preclearance).

Getting Around at Sea-Tac International:  Concourses A, B, C & D are 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.

1. To connect  between terminal and between gates
, you can take the STS train to/from the Main Terminal's North Station to/from its South Station. To avoid a lengthy walk from the Main Terminal to the Concourses and satellite gates, use the shuttle train:
(a) the South Train Loop between the main terminal South station and the B & S Gates;
(b) the North Train Loop between the main terminal North station and the C and N gates; and
(c) the shuttle train between North & South Terminal Stations with connections to N & S Gates:
(i) To connect between the N gates and the S gates, take the train from South or North Satellite to the 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.
(ii) If you need to travel between the South Satellite & Concourse C, take first the train from the South Satellite to the Main 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.

2. 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), and (from here on procedures differ): (a) 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 luggage at the Baggage Claim carousel 1. (Ground Transportation Information Booth is on level 3 of the parking garage.)
(b) If you need to transfer to a domestic flight at Sea-Tac International, you must recheck your luggage 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.

United, SkyWest & Air Canada Jazz moved from North Satellite to Concourse A.
Hawaiian moved from Concourse A to the South Satellite.
