SYDNEY (Reuters) - Boeing Co. (NYSE:BA - news) won a $10 billion order from Qantas Airways Ltd. (QAN.AX) to deliver 65 Boeing 787 Dreamliner jets, with an option for a further 50 planes, dealing a blow to rival aircraft maker Airbus.

Qantas, the world's eighth-biggest passenger airline by market value, said it ordered 45 twin-aisled B787 jets with options for an additional 20.

The value of the 65 B787s was A$13 billion ($10 billion) at list price, Qantas said, adding it also took out purchase rights for an extra 50 B787 aircraft. The actual purchase prices of such major deals are typically made at a discount to the list price.
