I'm not sure if MKE was "definitely underserved" in the early 80's or not. MKE has been one of those cities that served as a mini-hub or focus city for many carriers over the years (pre and post deregulation). During the time when they have served as a mini-hub/focus city, the number of nonstop cities served has increased. Otherwise, it decreases.
During the early 80's, SEA -- for example -- had difficulties supporting one year-round non-stop to JFK. However, SEA has grown over the years (and air travel has increased in general). Now, SEA has over a dozen nonstops into the NYC area, including EWR. So, MKE's number of flights has historically depended on airline hubs.
