Shanghai Airlines
After the merger with Shanghai Airlines, China Eastern Airlines signaled that it would combine the two carriers' cargo subsidiaries as well. The airline's new subsidiary cargo carrier, consisting of the assets of China Cargo Airlines, Great Wall Airlines and Shanghai Airlines Cargo, commenced operations in 2011 from its base in Shanghai, China's largest air cargo market. China Eastern Airlines signed a strategic cooperation framework agreement with Shanghai Airport Group, which controls both Shanghai Hongqiao International Airport and Shanghai Pudong International Airport. The airline will allocate more capacity to Pudong Airport to open more international routes and boost flight frequencies on existing international and domestic trunk routes.
