China Postal Airlines (CF, Nanjing) and Air China Cargo (CA, Beijing Capital) signed a strategic cooperation agreement on August 16 in which Air China Cargo will, over the next two years, provide cargo charter services to China Postal Airlines using its four B757-200(PF)s. The first aircraft is expected to be in place by late 2013. The four freighters are expected to help China Postal Airlines to meet soaring demand in the domestic Chinese Express Mail Service market and will help solve mismatches between capacity and traffic volume on some routes caused by the restriction of its own Boeing 737 Freighter fleet.
