Not to be confused with the inflatable palaces that parents rent for kids' birthday parties, Aircastle Limited is an aircraft leasing concern. The company owns a lineup of utility jet aircraft that it adds to, leases, and sells to passenger and cargo markets. Aircastle touts a portfolio of nearly 160 aircraft, which are leased to about 50 customers located in roughly 30 countries. Lessees of Aircastle's aircraft maintain the planes, as well as pay operating and insurance expenses. Aircastle also invests in industry-related assets, such as financing vehicles secured by commercial aircraft.
