AerCap Holdings N.V. operates as the world's largest aviation leasing company, maintaining a portfolio of commercial jets, engines, and helicopters. The company's core business model involves purchasing aviation assets directly from manufacturers and subsequently leasing them to a diverse customer base of approximately 300 airlines and cargo operators globally. AerCap generates the vast majority of its revenue through basic lease rents, supplemented by maintenance receipts and the strategic sale of older aircraft and parts. The company significantly expanded its scale through the acquisitions of International Lease Finance Corporation (ILFC) in 2014 and GE Capital Aviation Services (GECAS) in 2021. By providing flexible fleet solutions, AerCap allows airlines to modernize their fleets and manage capacity while mitigating the financial risks associated with outright aircraft ownership.
