BEIJING (Reuters) - Boeing BA.N and Okay Airways, China's first privately owned airline, have finalised an order for five 787-9 Dreamliners for $1.4 billion, Boeing said on Thursday.

The new order will strengthen Okay Airway’s plan to expand into the long-haul market, the official Xinhua news agency quoted Okay Airway’s president Li Zongling as saying.
