I fly AA about 1/4 of the time and am not a frequent business traveler anymore so I gave up on chasing status but AUS is my home airport and AC membership from the world elite card has been great since there's only one terminal here. I'll definitely give up the card when it comes up for renewal. The UA lounge is right next door to the AC so I'll get a membership there since they don't care who I'm flying (for now). No priority pass or centurion club here. DL is opening a lounge soon but according to this thread it's only for those flying DL. I wouldn't have a problem paying more for AC access if it didn't have the AA/OW BP requirement.
