They would get Oneworld Ruby, which from my understanding is fairly worthless (someone will certainly correct me if they disagree). If you know a solo traveler, it would certainly be a bigger benefit to them. The one caveat is that it won't really help a solo traveler who flies on paid first class tickets. I gave mine to someone who does just that and it really provides no benefit to them.
