Also for KC, they likely get a significant number of people from smaller metros around them that have minimal to no air service that while not part of the metro population, is more or less the same market for air service like St. Joseph, Lawrence, and even Topeka. Here its likely most of the demand is strictly the metro area. The small difference can likely also be explained by its a lot less practical now to fly to Chicago than in the past from here, while its still a much better option than driving from KC. Since a lot of local demand especially before 9/11 was to there, and has since dropped significantly due to TSA along with higher speed limits on highways and faster train service. Since a lot of the places that have higher overall demand is due to having a very high frequency shuttle type route there which has high local traffic.
