GECAS, the world's largest aircraft leasing company, announced an order for 40 Boeing medium-haul passenger jets on Monday, in a fresh boost for the U.S. planemaker's best-selling model.
Confirming an earlier Reuters report, GECAS said the order would be split between the current-generation Boeing 737-800 and the future 737 MAX, a revamped jet designed to save fuel with the introduction of new engines, starting in 2017.
GECAS is owned by General Electric, which makes the engines for the 737 family in a transatlantic joint-venture shared equally with France's Safran.
In October 2012, GECAS ordered 75 Boeing 737 MAX jets and 10 current 737-800s and took options for up to 15 additional 737-800s. Boeing's 737 competes with the Airbus A320.
GECAS was formed in 1993 after GE acquired most of the aircraft of the collapsed leasing empire of Irish entrepreneur Tony Ryan and combined it with its own Polaris operation. Most of its 1,700 aircaft are still managed in Ireland.
Ireland this week celebrates its re-emgerence as a major finance hub after AerCap, which owns the rump of GPA, bought its U.S. rival ILFC.
Following completion of the deal, both AerCap and GECAS will hold most of their aircraft on the books in Ireland, which is attractive to leasing companies because of a 12.5 percent corporation tax and a global network of tax deals.
