General aviation FBOs (commonly in the U.S.) sometimes provide courtesy cars that can be used for free or little cost by flight crews mostly for short trip from the airport and the surrounding city area. Larger and better equipped FBOs may additionally offer food vending and restaurant facilities, ground transportation arrangements by taxi/limousine, shuttle van, flight planning and weather information areas (computer- or telephone-based), rest lounges and showers, aviation supplies shop (selling navigation charts, manuals, or in-flight comfort items), access to in-flight catering, and accommodations reservations or concierge services for both crew and passengers through a customer service representative (CSR).

At smaller airports, the FBO is often the airport operator or a flying club. United States Within the United States, the Federal Aviation Administration (FAA) regulates some activities that may comprise an FBO such as the authorization or repair stations, flight training, and air taxi/air carrier services, but there are no federal regulatory standards covering all FBOs.
