Boeing expects orders for the passenger version of its revamped 747 this year, it said at the Farnborough Airshow, adding the plane was gaining a following since it entered service.
"There are some very, very active campaigns right now," said Pat Shanahan, general manager at Boeing commercial planes.
"We expect a series of orders for the next few months and over the next year from all parts of the globe."
Boeing so far this year has booked no orders for the 747-8, its biggest passenger plane which competes with the Airbus A380.
Lufthansa took delivery of the first new 747-8 Intercontinental, an upgraded, stretched version of the classic 747, earlier this year.
In May, the head of Lufthansa's fleet management told reporters he was not happy with the weight of the jet, but added that would not restrict his airline's use of the plane.
