It’s always something of a surprise (to us, anyway, and we live here!) when we hear that Hartsfield Jackson International Airport is the world’s busiest in terms of passenger traffic.

But now the honor may be going to one of China’s newest airports.

CNBC reported that China opened Beijing Daxing Airport on Wednesday, the second international airport in the capital city. When it reaches full operational capacity, expected in the next several years, 100 million passengers are forecast to go through the airport annually.

“The International Air Transport Association expects Asia Pacific to be the biggest driver of air passenger demand in the 20 years through 2035.

Specifically, China will replace the U.S. as the world’s largest aviation market in about five years, the association predicts. The market is defined by traffic to and from the country, as well as domestic flights within its borders.”
