A Fixed Base Operator (FBO) is a service provider at an airport that offers various support services for private and general aviation aircraft. These services typically include fueling, hangaring, maintenance, and flight planning assistance. FBOs play a crucial role in ensuring that aircraft are ready for flight and that passengers have a comfortable experience while at the airport. FBOs are often located at larger airports and may provide amenities such as lounges, conference rooms, and rental cars for travelers. They cater to both pilots and passengers, making air travel more convenient and efficient. Many FBOs are independently owned, while others are affiliated with larger aviation companies or networks.
