SEA Terminal Connections | iFlyer Forum

Vancouver airport has U.S. customs clearance - no need to to pass customs at SEA. What you need is to find out whether Alaska Air will automatically transfer your bags at SEA to Sun Country flight - not all airlines do, in which case you would need to take your bag and check it in with Sun Country before proceeding to your connecting gate: Alaska uses A, C, D Concourses & Satellite North; Sun Country uses Concourse A. - all concourses are connected at post-security.

What is U.S. customs clearance in Vancouver - can anyone use this - is there a charge? My luggage will not be transferred by Alaska Air automatically. Thank You.

1. As an international arrival, you arrive at the South Satellite, then go through immigration clearance, pick up cked bags, continue to customs, re-check-in your bags, go through TSA security screening (count on 30-60 mins)and then proceed to your connecting flight. 2. Alaska Airlines uses Concourses C & D with corresponding gates, as well as Satellite North (N gates). Look at your ticket and the overhead screens for your departing gate. 3. If transferring from South Satellite to North Satellite: After immigration take the subway - make sure to follow the transfer path, NOT the baggage stop. Take the train to Transfer to North Satellite stop, walk across platform to transfer subway and take it to the next stop, then walk across platform, take the next train & get off at North Sattelite. It will involve 2 transfers and 3 trains, but only 15-20 mins. 5. 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. If your departure is in Concourse D, you can walk there from the C gates.

1. Make sure you use Edmonton's U.S. Customs Clearance, saving you time at SEA. At SEA, Alaska uses Concourses C & D and the North Terminal, while Delta uses the South Terminal. Look at your Ticket to see which gate you depart from at Edmonton (C, D or S gates?) Connections between them are complicated - I suggest you open www.ifly.com/sea & and choose 'Terminal Map' from Quick Links to the left. Below the terminal map you find the various modes of transfer options. Your time is very tight!

Alaska uses Concourses A & D and Satellite North. Look at your ticket.

You arrive at SEA at Concourse C, gate C10 and will need to transfer to the Delta flight at the South Satellite (S gates). Take the reverse course of this direction: 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. Signs will guide you from the C gates to the Satellite gate. One hour should suffice.

Horizon uses Concourse C of the Main Terminal with gates C1-20; Delta uses the South Satellite with gates S1-13. On arrival use the shuttle train to the Satellite S gates. Follow signs. No time to waste!

Horizon now goes officially under name of Alaska Airlines (after merger); Alaska uses a number of gate areas - depending on where they come from: click on http://www.portseattle.org/Sea-Tac/Flights-Airlines/Pages/default.aspx?typ=A&fltnum=&city=&from=&to=&airline=QX&dt=04-07-2012 [change date if it's not today's] and add your details. American is in Concourse A. All concourses asre connected at post-security.

1. You arrive at SEA via Delta at the South Satellite which has a connector to Concourse A where you arrive via escalator between gates & transit level. Just follow signs, but hurry.

United uses Concourse B with gates B1-15 & Satellite North with gates N1-16. On arrival look and the overhead screens to find your flight number and departure gate; then follow signs. One hour transfer is enough.

1. The passenger terminal complex at SEA consists of a Main Terminal, divided by a central terminal area with four Concourses A - D, and the North & South Satellites: Shaped like a bow, Concourse B and South Satellite areto the left, Concourse C and North Satellite are to the right, and Concourses A & D are attached to the south ends of the Main Terminal. 2. Alaska uses both Concourses C & D (gates C1-20, D1-12) Delta uses the South Satellite (gates S1-13). (Check your ticket for gate numbers - while I have Delta listed for the South Terminal - this terminal serves all international arrivals). 3. All concourses are connected at post-security, enabling passengers to freely move around without having to leave the secured area. 4. Concourse A's escalator between gates & transit level takes you to the South Satellite. Concourse C has a connector to Concourse D at Horizon Air Special Services.

1. Assuming that your Canadian Airport has U.S. customs clearance, you won't have to undergo this procedure arriving at SEA. Horizon serves both Concourse C (and Satellite South - if you don't have U.S. pre-clearance), while Alaska uses Concourse D. All concourses are connected at post-security, enabling passengers to freely move around without having to leave the secured area. You won't need shuttles or trains to get there.
