In the past, I've booked several award tickets for my wife (who has no AA status) with my AAdvantage number in her record, and when her BP prints out, it's marked as Platinum. She got SSSS'ed once with this strategy out of about a half-dozen times I've done it, but the stamp on her BP was enough to get her into the AAdmiral's club when traveling without me. YMMV.
