The security line is in the general security area - the line for PremEx, 1K is to the right with a sign marked. UA gates are the N Gates.
I just recently moved to the SEA area, still trying to learn the lay of the land at SEA.
So the security lane is in the center of the terminal, and then I have to walk all the way back to the end to catch the train... hmmmm, ok, thanks.
