Boeing and the Lufthansa Group completed an order for four more 777 airplanes, valued at $1.4bn at list prices.
The purchase is part of the aviation company's plans to modernize its fleet with newer widebody airplanes.
"The order for the new long-haul aircraft highlights the strategy of Lufthansa Group to predominantly allocate the growth within its multi-hub system where cost and quality offer the best conditions for profitable investments," said the Lufthansa Group in a company statement.
The order provides two more Boeing 777-300ER (Extended Range) airplanes for Swiss International Air Lines (SWISS), the national carrier of Switzerland and a member of the Lufthansa Group.
SWISS currently operates 10 777-300ERs. The airline says the 777-300ER has served as the backbone of their long-haul fleet and the additional airplanes will allow them to further expand their network.
The order also provides two more 777 Freighters for Lufthansa Cargo, which serves nearly 300 destinations.
The 777-300ER can seat up to 386 passengers in a three-class configuration and has a maximum range of 14 685 km. The 777 Freighter, the industry's largest and longest range twin-engine cargo jet, can fly 9 070km with a payload of 102 000kg.
