Boeing and Turkish Airlines have finalized an order for ten 737-800s and ten 737-900ERs, the manufacturer announced today. Now flying 66 Boeing airplanes, including 58 Next Generation 737s, Turkish Airlines has yet to take delivery of a 737-900ER. Boeing places the value of the order at $1.6 billion, based on current list prices. The company had already posted the order on its orders and deliveries Web site as one held by an unidentified customer.

The new airplanes will come equipped with the 737 Sky Interior, which incorporates a new curved architecture, LED cove lighting, larger, pivoting stowage bins, sculpted sidewalls and window reveals and more intuitive passenger service units.
