What is the best option for SEA flyers?

I am trying to find the best airline to status match with for a SEA-based flyer. I do fly one or two transcons a year in PEY, and around two intercontinentals a year in PEY/ Business.

I am thinking of AS (and that will perhaps give me more chance to try perhaps try out JL. LOL Although I was a one world flyer with CX/AA for many years and dislike CX quite a bit).
