An FBO is a fixed-base operator, which is a company that is given permission by an airport to operate on its premises to provide aeronautical services for aircraft, passengers, and crew. Generally, FBOs are the main providers or Handling Agents, of services in general aviation, or for private and recreational flying. They’re usually found at public airports but can sometimes be found in a property next to the airport. FBOs at larger or higher-traffic airports are usually private companies. At smaller airports, FBOs are sometimes run by the local government.
