The twelve months to 31 December 2013 saw Air China Cargo's available freight tonne kilometres (AFTK) hit 8,664 million, a year-on-year increase of 2.3 per cent, while its revenue freight tonne kilometres (RFTK) rose by 0.1 per cent, year-on-year. The cargo and mail load factor fell by 1.2 percentage points to 57.8 per cent, reports the airline, while the cargo yield fell by 6.5 per cent to 1.57 renminbi ($0.2). In a bid to address difficult market conditions, Air China has rethought its strategy, giving it a renewed emphasis on what the airline described as, "enhancing the core cargo operations and developing the logistics value chain in order to push forward the transformation of the business model and cargo services."Consequently, the airline has optimised cargo routes, strengthened the sale of bellyhold spaces, and embarked on new long-haul flights to Europe and the US, to expand its international cargo network. Air China says it has introduced "competitive value-added" and transfer products, and is gradually replacing its Boeing 747-400 Boeing Converted Freighter with Boeing 777 Freighters. "These initiatives effectively mitigated the pressures facing cargo operation and reduced the loss", says the airline. Air China's group turnover in 2013 was 98.1 billion renminbi ($15.9 billion), a year-on-year decrease of 1.3 per cent. Profit attributable to shareholders fell by 32.2 per cent to 94 billion renminbi.
