Lufthansa, Germany's biggest airline, said Thursday it has placed orders for 59 new fuel-efficient long-haul aircraft worth a total list price of 14 billion euros ($19 billion).
Lufthansa said in a statement it has ordered 34 new Boeing 777-9X jets and 25 Airbus A350-900 to renew its fleet.
Delivery is scheduled from 2016, the statement said.
The order -- described by Lufthansa as the single largest investment ever made by a private investor in Germany -- will build a fleet of more fuel-efficient aircraft to combat high oil prices.
"With these aircraft, we make a quantum leap in terms of efficiency," chief executive Christoph Franz told a news conference.
