I think that was a poorly illustrated point made by BS. I suspect what he was trying to say is that #71 (CVG73NA) did not have enough (i.e., any) MDs in. Because there is no "next lower" category in CVG, he would fall under the second prong of 22.F.14 - which says that a pilot "will, at Company option, be assigned into any position at another base that his seniority would permit him to hold." That pilot would seem to be UNA until the company manually places him into any position that his seniority allows which, at #71, is any open category. I hope he isn't one of the rumored "12" that didn't have enough in. Of course, he is retiring in July and they have to convert CVG73NA out of the category in inverse seniority order so he will be lonnnnng retired before that even became an issue.
