American Airlines will launch a new flight to Beijing from Los Angeles on November 5. The carrier had previously said it would use a 289-seat Boeing 777-200 on the route. American has invested in China Southern Airlines as part of the process to gain a slot at Beijing Capital International Airport. The US airline and China Southern plan a codeshare under the new investment, including connections to 40 destinations in China from Beijing. In its latest filing, American asked the DOT for a short-term extension to the start-up date for the Los Angeles-Beijing flights from the current September 16 deadline.
