Delta Air Lines has moved from Terminal 2 to Terminal 1 at Shanghai Pudong airport.
The transfer allows the US carrier to work more closely with its Skyteam codeshare partners China Eastern Airlines and its subsidiary Shanghai Airlines, providing easier transfers for passengers.
The relocation came into effect yesterday.
Vinay Dube, Delta's senior vice president, Asia Pacific, said: "By relocating our operations and growing our partnership with China Eastern and Shanghai Airlines, Delta will offer the most comprehensive intra-China network at Shanghai airport for our customers in the United States and China.
"For the past several years, Delta consistently enhanced nonstop service between China and the US, and we look forward to adding to our network new service between Los Angeles and Shanghai beginning in July."
Delta's daily service between Los Angeles and Shanghai, scheduled to launch on July 9, is subject to government approval (see news, January 15).
Dong Bo, China Eastern's chief marketing officer, said: "China Eastern Airlines and Delta are committed to becoming the leading partnership on trans-Pacific routes through more extensive and deeper cooperation.
"The codeshare between Delta and Shanghai Airlines will further enrich bilateral cooperation, products and expand the network."
This summer, Delta is operating 28 weekly departures to Shanghai and a daily service to Beijing from both Seattle and Detroit.
