At least the KCMO voters approved an entirely new conventional design terminal to replace everything. In design phase. To be opened in 3 years or so. Keep your fingers crossed.

The current 3 horseshoe shaped terminals were built before any security screening existed. It is too narrow to have groups of screening and a wide area for people to walk, adequate restrooms, places to eat, etc. like DFW. TWA wanted them to fix it, they didn’t, so TWA moved its hub to STL. It left MCI with Braniff as a hub. Braniff went out of business. So, no hub. Southwest has grown to be the largest carrier at MCI. It had finally got so painful the airlines and the city decided to do something about it. . .after 50 years.
