Just operations wise, I cannot believe anybody can operate an effective hub in MCI. I was suprised when I went thru there that you have to leave the secured area to visit the rest room and concessions, plus it seemed like every three or four gates had there own security line. So unless your connection happenes to be one of the neighboring gates you have to leave the secured area and go back thru security. Seems like the airport should consider fixing that but it would take a major investment. Is it that way in all of the terminals or just in the YX terminal?
