Lufthansa has firmed up its agreement with Boeing for five 777 freighters but will not make a decision on whether the aircraft will operate for its Lufthansa Cargo division or its AeroLogic venture until closer to delivery time.
The aircraft are scheduled for delivery in 2013.
Lufthansa said a decision on who will operate the freighters will be made "close to delivery, when we see where the demand is", adding that "we need to be flexible on this".
The German carrier announced its intention to order the aircraft in March 2011.
It already operates the 777F through its Lufthansa Cargo-DHL joint venture AeroLogic.
