BEIJING - SF Airlines, China's largest cargo airline, has seen its fleet expand to 60 all-cargo freighters, according to the cargo airline Monday.

The latest member of the fleet is a B757-200 all-cargo freighter, which is the second freighter the company received this year.

The expansion of the fleet will strengthen the airline's capacity to meet the upcoming peak season of the express delivery business and help the airline to optimize its air route network and better serve the market.

SF Airlines, the air cargo branch of China's express delivery giant SF Express, is the country's first private express airline. It has created an air cargo network nationwide and committed to extend it worldwide.

SF Airlines will continuously improve air cargo transport capacity and deeply integrate into the construction of global logistics supply chain, said the cargo airline.
