How long is a direct flight from Kansas City to Birmingham Alabama?

The major airport serving both Kansas City, MO and Kansas City, KS is the Kansas City International Airport (MCI) in Kansas City, MO. Non-stop flights are difficult, if not impossible to find between these two airports, but a one-stop flight, which is most common, averages 3 hours 45 minutes to 4 hours 30 minutes depending on the carrier, the layover and the actual jet. Weather can affect this flight time, too. And, if you are instead flying from a smaller municpal airport, the flight time would also be increased.
