It looks like the north security checkpoint for the D&N terminals has reopened. I saw this snipet on alaskaair.com today:

SeaTac Security Checkpoint Advisory
Updated: November 1, 2010

The North Security Checkpoint at SeaTac (D gates) have re-opened after the installation of Advanced Imaging Technology (full body) scanners. Please allow additional time for screening if you are using this checkpoint.

I don't think I have been to Seattle airport since 1986 - a long time. What are security lines for Alaska like on a Sunday evening? I have a 7:40PM flight to the SF Bay area.

Thanks in advance.

SeaTac Security Checkpoints
 

Hi -
I am trying to figure out how many primary (excluding FIS) checkpoints are at SeaTac airport. According to the MYTSA app, there is a checkpoint for the North Terminal, South Terminal and then 2 for the Main Terminal (Central Checkpoint and Charlie Checkpoint). But the map at SEA's website shows 3 checkpoints for the Central Terminal. Any locals have good insight if there are 2 or 3 in the Central Terminal? And if so, which one is the one that MYTSA refers to as the Charlie Checkpoint?
Thanks so much!
Dan

There are five checkpoints into the main terminal. The north and south satellites do not have independent checkpoints, those are just the two into the main terminal that are closest to their respective shuttle trains.

I'd assume that Charlie Checkpoint is #4, at the foot of C concourse. A/S is #2, Central is #3 and D/N is #5. Checkpoint #1 is rarely open, peak periods only.

This is very helpful - thank you!

There are 3 checkpoints at SEATAC you can use...one is usually closed. It depends on when you are flying out which one that is.

Usually one of these checkpoints is closed.

The terminal is a parabolic curve shape where two checkpoints are near the ends and the third is in the middle.

There are two exit points from the terminals when you exit to go to baggage claim. These are in between the checkpoints.

To get to North and South Satelites you MUST take the tram that connects to them.

The reason you may have confusion is because on South terminal there is a customs office...non-Canadaian international flights generally arrive here.


As far as the airlines go on these charts...that is in a state of flux right now where airlines will be shifting quite a bit over the next 3 years.

I'm confused about the statement that there are 3 checkpoints and that usually one of them is closed. In my experience, the north and south checkpoints as well as the one the exits into the food court between Terminals B and C are always open. Perhaps they have one closed either very early or late. There is another checkpoint that is often open that exits close to Terminal C near the Alaska Airlines Board Room.
