German flag-carrier Lufthansa is set to order 30 Airbus A320neo-family aircraft as well as five Boeing 777 freighters for its cargo operations.
It is taking five A321neo and 25 A320neo twinjets.
Lufthansa has not disclosed an engine selection for the aircraft, the re-engined version of the baseline A320.
The carrier says the order, worth around $4 billion at list prices, has been approved by its supervisory board. Deliveries of the aircraft will begin in 2016.
"The orders are yet further steps in Lufthansa's ongoing fleet modernisation and expansion policy," says the carrier.
Lufthansa's additional 777Fs will join the fleet in 2013. The type is powered by General Electric GE90s.
It already operates the 777F through its Lufthansa Cargo-DHL joint venture AeroLogic.
Lufthansa Cargo also has a fleet of Boeing MD-11 freighters. The airline says the new 777Fs will provide greater fuel efficiency and create lower noise levels.
