Boeing has increased its 737 Next Generation backlog with an order for eight aircraft from an unidentified customer.
The order for eight was added Thursday along with three 737-700 aircraft for Turkmenistan Airlines and a further backlog reduction of two 777 aircraft.
The increase brings Boeing's total 2009 orderbook to 161 gross orders and 91 cancellations, giving the American airframer a total of 70 net orders on the year.
Of those 91 cancellations, 73 come from the 787 backlog, which still remains at around 850 firm orders.
Boeing delivered 28 aircraft in August, a drop of 22% after deliveries fell by eight year-over-year. August orders slipped 11% from 36 a year ago to 32 in 2009.
