"BEST AVIATION NEWS" Air China confirms deal for four 777-300ERs Boeing has confirmed that Air China ordered the four 777-300ERs that it added to its backlog last week as those from an undisclosed customer. Earlier this month, Air China said that it had signed a purchase agreement for the twin-jets, putting the value of the transaction at $1.15 billion excluding concessions. Delivery would be over the 2013-14 period, the Star Alliance member added. That deal has been confirmed, say Boeing and Air China. The Beijing-based carrier says that 777-300ERs will be the "backbone" of its long-haul fleet. "The airplane's high efficiency and performance features will enable Air China to launch more direct long-haul routes to meet the increasing demand of our passengers," adds Fan Cheng, Air China's vice-president. All 777-300ERs are equipped with General Electric GE90 powerplants.
