Lufthansa has announced a 59-strong widebody aircraft order encompassing 34 Boeing 777-9Xs and 20 Airbus A350-900s. The airline said the first of the new aircraft would be delivered in 2016, with older Boeing 747-400s and Airbus A340-300s being phased out of its fleet by 2025. The new aircraft are intended to “primarily” replace existing aircraft. The order totals €13bn at list prices and Lufthansa says it is the largest single private-sector investment in the history of German industry. The A350s will be powered by the Rolls-Royce Trent XWB, while the 777-9Xs will be powered by General Electric's GE-9X.
