The Boeing Co. and Turkish Airlines have signed an order for five Boeing 777-300ER (extended range) airplanes valued at $1.36 billion at current list prices.

This is the first time Turkish Airlines has purchased new 777s directly from Boeing. The airline currently operates a fleet of 65 Boeing airplanes, including Next-Generation 737s and leased 777-300ERs.

The Boeing 777-300ER is 19 percent lighter than its closest competitor, greatly reducing its fuel requirement. The airplane can seat up to 365 passengers in a three-class configuration and has a maximum range of 7,930 nautical miles.
