SF Airlines, China's largest air-cargo carrier, has expanded the size of its freighter fleet to 80.

The cargo carrier received a Boeing 767-300 widebody freighter on March 26 at Shenzhen Bao'an International Airport and joined the fleet of SF Airlines, state media reported.

The day of the aircraft delivery also marked the 30th anniversary of the founding of SF Express.

Headquartered in Shenzhen, SF Airlines was founded in 2009 as China's first private air express carrier, and around 30% of its freighters are widebodies.

The expanding fleet helps SF Airlines to enhance the air express capacities on the network at home and worldwide.

It is currently operating 150 cargo flights each day on average.

Xinhua said in its report that SF Airlines would continuously expand its fleet size and strengthen its air-logistics service capacities.
