Because NetJets is not an aircraft manufacturer, they independently choose the very best aircraft available today. The NetJets fleet, which stands at more than 500 aircraft, boasts an average age of 3 years old, which is significantly younger than the 16+ years average age of all business jets currently in use. All scheduled aircraft maintenance is done by manufacturer certified facilities and is overseen by a team of over 200 NetJets quality control, technical and maintenance supervisors.
