American Airlines and Beijing-based Hainan Airlines have implemented their new codeshare agreement, providing significant growth opportunities for American in China and for Hainan in the United States. Customers can now book these new codeshare flights for travel beginning March 25. The codeshare relationship complements American\'s existing service to China. Currently, American operates nonstop service in three U.S.-China markets: Chicago O\'Hare-Beijing, Chicago O\'Hare-Shanghai and Los Angeles-Shanghai. American and American Eagle offer more than 450 daily departures from Chicago O\'Hare, and nearly 150 daily departures from Los Angeles. The codeshare agreement includes:     Display of AA\'s flight numbers (AA*) on Hainan flights between Seattle and Beijing as well as on Hainan flights beyond Beijing to Fuzhou, Guangzhou, Hangzhou, Kunming and Urumqi.     Display of Hainan\'s flight numbers (HU*) on American flights between Chicago and Beijing and Shanghai, Los Angeles and Shanghai, as well as on American flights to and from 12 other cities in the U.S. \"We look forward to working with our new partner, Hainan, to provide even more international travel options for our joint customers,\" said John Bowers, American\'s Managing Director of Asia / Pacific – Strategic Alliances. \"China is one of the world\'s fastest growing travel markets, and this new codeshare relationship will give our customers opportunities to connect to new destinations throughout the country.\"
