I found out that over the next year, I'm going to be traveling between SEA and LAX at least once a month.

I'm an Admiral's Club member, but that doesn't help me for Board Room access in either LAX or SEA for AS flights.

As far as I can see, there are three options for getting access:

1. Buy the regular Board Room membership (I have zero AS status, although I probably did fly over 25k on AS this year - I needed all that to requal for Exec Plat on AA)
2. Priority Pass membership
3. AMEX Platinum

Is there another option? Have AS partner elites ever been able to negotiate a discount on memberships?

If AMEX had maintained its relationship with Admirals Club, this would be a no-brainer, and it still looks like it may be the best option considering the $200 credit to offset the $450 fee.

Any advice is appreciated.
