China's BOC Aviation has ordered 43 Airbus single-aisle A320 passenger jets worth more than $4.1 billion (3.0 billion euros), the European planemaker said on Tuesday, amid booming Asian demand for air travel.

BOC Aviation, the Singapore-based aircraft leasing arm of Bank of China, has ordered seven A320neo aircraft and 36 A320ceo jets, Airbus said at the Farnborough airshow near London.

"It's great to see one of the world's leading lessors, BOC Aviation, based in the fast growing Asian market, continuing to invest in our market leading A320 family," said Airbus president Fabrice Bregier.

"This tells us that not only are our aircraft universally recognised as the industry's benchmark for efficiency, comfort and reliability, but also underlines the financial community's confidence in the A320 Family as a sound financial asset."

BOC Aviation chief executive Robert Martin added: "By adding this order to our pipeline for the next five years, we are confident at meeting the needs of airlines which are expanding or replacing older fleets."

BOC Aviation has a fleet of 251 aircraft, which includes 109 Airbus aircraft operated by 27 airlines.
