KC is a great get-out-and-go airport but it's terrible airport to have a layover in. It was designed to be the most efficient airport in the country in the era before security screenings were a normal thing. Pre-9/11 airport security put somewhat of a damper on this, but it was made many times worse when the TSA came into being and implemented the concept of "sterile areas". Now, if you get a layover in KC, you're literally stuck in a glass box with five gates, a juice cart, and a bathroom for its entirety (unless you wish to dirty yourself with the non-sterile area and go through security again).
