This month I flew from Baltimore to Salt Lake City on Southwest with a stop in Kansas City. MCI needs to be updated - you have to go through security at each set of gates because MCI was designed so that you can drive right up to the gate. This is inconvenient for passengers like me who were connecting and there's no concessions or restrooms when you get to the gates which can be quite a bummer especially if your flight is delayed after you get to the gate. Also the lighting was dim and the terminal looked old and I wasn't impressed with the variety of concessions. If a new redesigned terminal were built MCI would be a great place for an airline hub as it's within 2-3 flying hours of anywhere in the continental U.S.
