So, I was reading up on air travel in China as I was stuck at the Kunming airport with a weather delay tonight. I came across an article about a second major airport in Beijing that could essentially bypass Beijing Capital International Airport as the primary airport in Beijing, though it's intended to serve the southern parts of Beijing as well as Tianjin and Hebei. I'm a bit behind the times on this one as the most helpful article I came across is from 2015. The airport is currently under construction.
Beijing Daxing International Airport (placeholder name, I think)
Check it out at this link. Pretty sweet, if you ask me.
