Branson Airport BKG is serviced predominantly by Southwest but not exclusively.  It is a very small airport with only 4 gates and 1 luggage return.  It is incredibly charming with a western motif.  It has one restaurant - Famous Dave's and a gift shop with some food. 

There is a car rental located here but Avis/Budget (same) has a shuttle to their location at the Taney airport.  It's an easy ride and location.  A GPS may give strange directions from this airport  so be prepared to use a map if you have a similar problem.  There is a desk located at the airport to direct you to transportation.  A car is necessary in Branson.
