Beijing Capital International Airport is the busiest airport in Asia and the second busiest in the world. But in 2002, the airport was only the 26th busiest airport in the world. But in the last 16 years, the airport has more than triple its passenger count. Although Beijing Capital International's passenger traffic has grown in leaps and strides, it is unlikely to overtake Atlanta International Airport as the world's busiest in the near future. That is because the airport is already near full capacity, and Beijing will soon open a second international airport called Beijing Daxing International Airport in 2019. On a side note, the IATA Airport code for Beijing Capital International is PEK, which is based on Beijing's old romanized name, Peking.
