I had a great trip to Vegas getting bumped (my wife and I both) each way for free vouchers from united. This got me thinking what is the busiest airports with the best chance of being bumped? My wife moonlights and we are from kentucky so everything is a connecting flight for us with multiple options including CVG ORD Memphis, etc She is starting to moonlight in MCI (Kansas City) any thoughts on the best spot to connect through for bumps?
