Recently, American Airlines was selected over Delta Air Lines to offer daily, nonstop, Los Angeles (LAX) to Beijing (PEK) flights. In March, both airlines applied to the US Department of Transportation (DOT) for the rights to fly direct route.
The DOT decided in American Airlines' favor, and it cited its superior connectivity between LAX and other destinations in the western United States. Provided there are no more delays, American Airlines will be the only US-based airline offering nonstop LAX-PEK flights
The airline will use a Boeing 772-200 on the route. Originally, it planned to begin offering flights in December, but the DOT selection process took longer than anticipated, so American Airlines will probably start offering the route in 2017. While American Airlines has been chosen, it's possible that there could be more delays as Delta has up till November 22 to submit an objection to the ruling.
Currently, the only airline offering the direct route is Air China and United codeshares, via Air China. American customers who want to fly to PEK airport from the U.S. can do so from Dallas (DFW) or Chicago O'Hare (ORD).
