US Airways said on June 23 that it had signed a code-sharing deal with Air China Limited that affects routes including Beijing-Los Angeles and San Francisco-New York.

US Airways will also put its code on connecting flights to Shanghai through Air China's Beijing hub under the deal.

Air China will put its code on US Airways flights from Los Angeles and San Francisco to Phoenix, Arizona; Las Vegas, Nevada; Charlotte, North Carolina; and Philadelphia and Pittsburgh, Pennsylvania.

"We continue to expand our network across the Pacific through our codeshare partners. Air China provides our customers with three US gateways to Beijing and Shanghai, and we now have codeshare arrangements to over 20 destinations in the Asia-Pacific region," said Andrew Nocella, US Airways' senior vice president.

The two airlines are part of the Star Alliance.
