Aviation express sector taking off

China's aviation express sector is taking off as major delivery players expand their fleets, but industry experts said it is just the beginning of the industry's full-blown development.

The 45th all-cargo plane of SF Airlines Co Ltd, the aviation branch of China's express giant SF Express Co Ltd, arrived at Shenzhen Bao'an International Airport and entered operation on July 1.

The Shenzhen-based company owns the largest freight fleet in China. With its nationwide and global network, SF Airlines has transported around 2 million metric tons of cargo since it began operating in 2009.
