BOC Aviation has delivered the last of the eight 777-300ERs ordered from Boeing for long-term lease to Thai Airways, the company announced on Thursday.

The transaction marked the first time BOC Aviation had worked with the Thai national carrier.

"The size of the order and financing of a stream of wide-body deliveries demonstrate BOC Aviation's strength in helping customers manage risk on their balance sheets over an extended timeframe," said Robert Martin, managing director and chief executive officer of BOC Aviation. "So they can focus their financial resources on operations and expansion."

BOC Aviation is wholly owned by Bank of China Co Ltd. To date, it has delivered a total of 31 Boeing 777 aircraft.
