A fixed-base operator (FBO) is a service provider at an airport that offers various support services to private and general aviation aircraft. These services can include fueling, hangaring, maintenance, and flight planning assistance. FBOs are essential for ensuring that aircraft are ready for flight and that passengers have a comfortable experience while at the airport. FBOs often provide amenities such as lounges, conference rooms, and transportation services for passengers and crew. They play a crucial role in the aviation industry by facilitating the operations of private jets and other non-commercial aircraft, contributing to the overall efficiency of air travel.
