I hope it's just a training issue. These lounges love to make up rules that "are so new they aren't published yet". Yet if they truly wanted to deny access under published policy they could just do so on the basis of capacity like so many US BA lounges do. I'm not too far away from becoming QF SG and a few more months to WP (Already AA EXP for another year). I fly a lot of domestics out of LAX. It's going to be interesting to see the consistency of access.
