HK-UMICH, the AA SOS coupons seem to be sent out randomly to Gold and above AAdvantage members. Since I've become a less-than-Gold member I haven't received any and I received them about once a quarter when I was Gold. I sometimes forget to take them with me, but I did offer two to a great FA on a flight to Honolulu once. Just before we landed, she brought us a nearly full bottle of wine saying she'd have to throw it away otherwise. We accepted happily.
