The contract is being finalized at this stage. The related order and delivery details are expected to be soon published on its official website after the deal is approved.

"Air China will carry on the traditions it has since it began operating the Boeing 747 family in 1980s. The newest and high-capacity Boeing 747-8 intercontinental passenger jets are able to provide passengers with impressive flight experiences as well as offer exceptional fuel economy," said He Li, vice president of Air China.

Air China, as China's leading air carrier, intends to use this batch of jumbo jets to expand its international routes.

"Depending on its advanced technology, the 747-8 will provide better operating economics, higher efficiency and better environmental performance to support the continued development of Air China. Air China has now become the world's fastest growing and one of the largest airline companies. We are very proud to contribute our power to their success. We also look forward to continuing our long lasting partnership," said Marlin Dailey, sales and marketing vice president of Boeing Commercial Airplanes.

The 747-8 is able to carry 476 passengers with its three-class configuration. It adopted a new wing design and upgraded cockpit. It also adopted the interior features of the 787 Dreamliner, including the arc-type and upward-bending new structure, which can make passengers feel more open and comfortable amid the increase in luggage space.

In addition, the lighting technology also highlights the advantages of this structure as the soft lighting allows passengers to get better rest during the flight.

The Genx-2B engines use the 787 technology, which reduces aircraft noise and emissions. It also possesses unsurpassed fuel economy. Meanwhile, its freight volume will increase by 26 percent.
