I do agree that it's puzzling that they are dropping STL for MDW for some stations while doing the exact opposit and dropping MDW for STL in others. My hunch would be that connecting the small Midwest stations to MDW would be the best bet to maximize connections and O/D. It *almost* seems like this release is incomplete and that those flights were omitted but I really don't think that's the case. Back when BKG was still around there was an erroneous release that showed it as having 0 flights leading many to believe that it was going to be dropped which was not the case, at least not at that moment. Of course it did eventually end up getting the hook but that was down the road a bit.
