SEA Terminal Connections | iFlyer Forum

All the baggage claim and ticketing areas are connected. So you can easily just claim your baggage from your AS flight and walk to the BA check-in counter to check it. Note that due to your long layover the BA counter may not be open yet.

Wouldn't there be quite a distance to walk between the two terminals? If so, is it possible to take the airport transit train?

They do not share the same concourse but all the gates at SEA are connected beyond security.

I suggest you conact SEA at 206-787-5388 or at http://www.portseattle.org/About/Contact/Pages/Contact-the-Port.aspx

I doubt you will be able to check the bags at the gate (you might get lucky and they will let you). I would schedule at least 2 hours to make your connection. Preferably 3.

At SEA, to connect between the N gates and the S gates, take the train (near gate N10, down one level) from North Satellite to the Main Terminal, then cross over and take the train on the opposite side to the North Satellite stations & take escalator up. My guess is 25-30 mins.

Thanks for the info.

Was your ticket bought on one reservation? If so you probably won't have to claim your bags in Seattle. I believe all gates in Seattle are connected beyond security so you won't have to go through any security there either.

At SEA, Hawaiian uses Concourse A (A gates), while Alaska uses Concourses D, C and Satellite North (N gates). 10 mins transfer seems to be not enough. I suggest you open www.ifly.com/sea; then click on 'Terminal Map' under QUICK LINKS and scroll down to the detailed text.

Well it does say 'based on historical averages', and as a frequent traveler I'd say they're pretty close. HOWEVER, they're only pretty close for certain days of the week. Try flying Monday before 9am and you'll run into the east-coast crowd starting their week. Saturday afternoon? Not so much of a problem. They need to show average BY DAY. And please, could you decifer the check in lines are called? Not everyone knows the name of the entrance by the food court with twice as many metal detectors as the other entrances!

*decipher what... (can't spell or type today)

That's probably enough time, but try pricing it as a multi-city itinerary on AA.com or an online travel agency and see if you get the same price. If you do that then your bag will be checked through to FAI and you won't have to worry about claiming it in SEA.

Thanks. That makes sense. I'll go thru AA.com.

You arrive at SEA from CDG at the South Satellite's Gate S2, and depart from the Main Terminal's Concourse B, gate B3. On arrival, you go through immigration clearance, pick up checked luggage, continue to customs & recheck your luggage and go through TSA security screening prior to proceeding to your connecting flight. To get from the South Satellite to the your connecting Alaska flight, you need to take the South Train Loop to the Main Terminal and head for Concourse B. Estimated transfer time: 1 hr 15 mins. at most. Caution: If AF does not transfer bags to Alaska flight, you would have to take them to main terminal & check them in there.

He arrives at Concourse C, Gate C-2C & departs from gate C15 (Horizon merged into Alaska, & gates are listed under Alaska). (Concourse C has gates C-2A through C-2M and als gated C3 to C 20.

You'll clear US Immigration and claim and recheck your bags with Alaska Airlines in S-Satellite. Then you'll go through security again and take the train to the main terminal and walk to Concourse C where your flight to Portland should depart from. It's a fairly involved connection that might take the full 1.5 hrs. Your connection in Portland should be easy.

At Vancouver, go through US Customs Clearance. On arrival at SEA, use the shuttle train between the main terminal's South station and the B gates (assuming that 'Terminal M' is the main terminal, which has Concourses A, B, C & D). You have enough time for transfer.

At SEA, international passengers arrive at the South Satellite (whether changing planes or ending their trip at Sea-Tac) and, if transferring to another flight, go through immigration clearance, pick up checked luggage, & continue to customs (taking 30-60 minutes). For domestic flight connection, you must recheck your luggage and go through TSA security screening prior to proceeding to your connecting flight. To get to Concourse A take the escalator up to the Main Terminal, proceed to the departures level, go through security check and on to Concourse A (gates A1-14.) You have enough time.
