One of the nice perks when I first purchased a (then) Boardroom membership was that you were able to get a "pass" to be able to get through security and go to the Lounge to meet folks that were passing through, departing or leaving SEA. That changed years ago and as I remember at the time it was due to people taking advantage of that. Not sure if that really was the reason. The policy then was that you had to have a same day boarding pass along with your Lounge card. However, since they have been going to biometrics, I have never been asked for my boarding pass at SEA, PDX or LAX; just go in, put my two fingers on the reader and receive a nice "welcome" from the staff. Maybe they are going back to asking for the boarding pass.
