In short, if you begin or end your trip in MCI , it's probably the single best airport in the country. Curbside to gate in 25 feet - an amazing and efficient design. However, this is accomplished by every gate area being in it's own sterile security area just off curbside, which poses the aforementioned headache for connecting passengers. KC, for whatever reasons, has never been good as a hub for airlines (recall back to Braniff 1 and 2, Eastern, US Airways, and the lowly and now defunct Vanguard Airlines), so most likely you're just an origin/destination passenger. The renovation has made it more up-to-date, better services and better aesthestic design. It still suffers from few services, in the gate areas though. Security can be odd - I was once told that I could wear my tennis shoes through the detector, but then pulled aside for complete pat-down because I did wear my tennis shoes (by the same guy who told me I could wear them, an then pulled me aside for the same reason)- where's the logic? Good airport nevertheless.
