International Lease Finance Corporation

John Travolta bought his own Boeing; if your company's cash flow is more limited, International Lease Finance Corporation (ILFC) will lease you one. The company, which leases the entire range of Boeing and Airbus commercial aircraft, is the world's second-largest lessor of new aircraft and widebody carriers. It boasts of owning the world's most valuable fleet of leasable aircraft -- about 930 planes. ILFC's airplane-parts management business maintains the aging aircraft in its fleet. Commercial airlines outside the US generate more than 95% of revenue; ILFC counts most of the world's airlines as customers. Parent AIG (American International Group) spun off ILFC's holding company, ILFC Holdings, as an IPO in 2011.
