Main Terminal / Concourses at Seattle Tacoma SEA Airport
Seattle/Tacoma’s Sea-Tac Airport consists of a Main Terminal, shaped like a bow, with Concourse B and South Satellite to the left, Concourse C and North Satellite to the right, and Concourses A & D attached to the south ends of the Main Terminal.
Getting Around at Sea-Tac International: All concourses are connected at post-security, enabling passengers to freely move around without having to leave the secured area. The satellites 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; the Main Terminal is also connected to the N and C gates at its North station, and to the S & B gates at 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 and the B & S Gates;
(b) the North Train Loop between the main terminal 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. (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.
The Main Terminal at Sea-Tac Airport consists of a lower level baggage claim level, a ticketing level and a Mezzanine. There are two Travelex foreign exchanges in the ticketing level (next to ‘Seattle’s Best Coffee’ & next to ‘Starbucks’) and one in the baggage claim area (near door 6). ATM machines are located throughout the Main Terminal pre- and post-security, and its concourses & satellites. The ticket counters 1 to 6 correspond to the skybridge numbers leading to the parking garage. Food & drink, as well as shops, are available in all levels & concourses. The baggage claim level has an Arrivals Hall with a Pet Potty outside near doors 00 and 26 on either side.
Concourse A of the Main Terminal has gates A1 to A14. Travelex foreign exchange is near the security check. Across from the food court are exits to the main terminal, and past gate A1 leads to the Central Terminal. An escalator between gates & transit level takes you to the South Satellite.
Concourse B of the Main Terminal has gates B1 to B15. An ATM cash machine is next to gate B3, a children’s play area, is next to the exit to the main terminal, with connections to both Concourse A and Central Terminal in the same area.

An ATM cash machine is opposite gate 8, Horizon Air Special Services are near the connector to Concourse D and the exit to the Main Terminal. Near ‘InMotion DVD Rentals’ you can connect to the Central Terminal. The Regus Business Center is at gate C3.
