Singapore Airlines Cargo (SIA Cargo) and China Cargo Airlines have begun putting their code on each others' services between Singapore and Shanghai from 26 June.
This is part of a broader joint services agreement that the two airlines signed in June.
SIA Cargo, a subsidiary of Singapore Airlines, and China Eastern Airlines' subsidiary China Cargo signed a joint venture agreement in 2010. SIA Cargo also has a 16% stake in the Chinese carrier.
"We have anticipated a greater partnership with China Cargo Airlines since we signed the joint venture agreement in 2010. The new joint service agreement provides more flexibility and better services to customers as it provides more choices of flights for air cargo shipments between Singapore and China," SIA Cargo president Tan Kai Ping said in a statement in June when the airlines signed the joint services agreement.
China Cargo Airlines' president Zhu Yimin, added: "The joint freighter services will enable the two airlines to tap into each other's network through our hubs in Shanghai and Singapore. There will be more direct access to destinations in domestic China on China Cargo's network whilst we will be able to tap on Singapore Airlines Cargo's network in the Middle East, Africa, Australia and Latin America, thereby providing a more comprehensive and extensive network for customers of both airlines."
Other initiatives undertaken by the airlines include enhanced system integration and a more integrated ground handling at the carriers' respective hubs at Shanghai's Pudong International airport and Singapore's Changi International airport.
