SEA, which is interesting because the #1 airline is not a transferrable partner (AS), the #2 airline is AMEX, and while AA, WN and UA aren't useless, they're not amazing, B6 is pretty much an afterthought. SEA has a lot of *A/OW/ST TATL/TPAC/ME action so all the transferrable partners are useful in some way, though you're not going to find a lot of three/four cabin F unless it's BA.
