Here is a collection of photos of the new Beijing Daxing International Airport, aka Starfish. As of late last month it has slowly been receiving domestic and now international flights. Nanyuan airport has now closed as a public airport with Beijing now serviced by the Beijing Capital Airport and the new airport at Daxing.
The airport has a lot of high tech features which is employed to make the traveling experience smoother.
Which airport should you land at? It will depend on your airline as some airlines will be exclusively based at Daxing and others at the original Capital airport. Transfers to and from the airport are slightly more convenient at Capital although there is the high speed rail that connects Daxing to Beijing West Railway station.
