GE Capital Aviation Services (GECAS) and International Lease Finance (ILFC) remain the two largest aircraft by fleet value and size, but the latest annual Airline Business leasing survey shows strong growth among the leading lessors behind.

The GECAS fleet, comprising over 1,750 aircraft as of the end of 2011, was worth around $34.6 billion - fractionally below figures for the same time last year. ILFC saw its fleet fall almost 5% on the same stage last year to $27.8 billion. Its fleet comprised in excess of 1,000 aircraft. This annual leasing survey was researched by our data team and compiled from Flightglobal's Ascend Online database.

Behind these two leasing giants AerCap, BBAM and CIT Aerospace all enjoyed double-digit growth in the value of their fleet to $8.5 billion, $7.8 billion and $7.5 billion respectively. Japan's Sumitomo, which also owns Sumisho Aircraft Asset Management, is also set to join the lessors at the top table if it completes a deal agreed earlier this year for RBS Aviation Capital - currently the seventh largest lessors in the world.

Outside of the top ten, a number of recent additions to the aircraft lessors ranks continue to make their mark. Air Lease, Steven Udvar-Hazy's high profile leasing venture, has already expanded its fleet portfolio from 36 to nearly a hundred and is now the 12th largest lessor by fleet value. Two other lessors, Avolon and Jackson Square, grew their fleet from nine to 51 and 46 respectively to break into the top 25 lessors by fleet value.

The total fleet value of the top 50 aircraft lessors was more than 10% higher than in 2010 at $171.4 billion
