Cargo volumes at Dubai World Central increased 7.8% to 54,000t in the first quarter compared with the same period a year ago.
Air traffic movements at the airport rose 17% to 4,100.
Dubai Airports - which owns and manages both DWC and Dubai International - predicts that its total cargo volumes will reach more than 3 million tonnes by 2015. "An increasing portion of that growth is expected to spill over to DWC," it adds.
Passenger operations at DWC are due to begin on 27 October, with launch carriers Wizz Air and Nasair.
