Traffic at the airport was up 1.9 percent between 2013 and 2014. Beijing (PEK), which comes in at second place with 86 million passengers, saw growth of 2.9 percent over the same period, compared to its previous years of double-digit growth.

"Passenger traffic remained resilient in the face of the global uncertainties that beleaguered many economies in 2013 and 2014," said Angela Gittens, the organization's director, in a press release.

"International tourism, in particular, was irrepressible in 2014 considering the geopolitical risks that have persisted in certain parts of the world, such as Eastern Europe and the Middle East. The Ebola outbreak also presented significant challenges to the aviation sector. Notwithstanding, by and large, the international traveler in 2014 appears to have been immune to these potential dangers."

Worldwide airport passenger numbers increased by 5.7 percent in 2014 to over 6.7 billion, per the report. The strongest growth in traffic came from Brazil, Russia, India China and South Africa.
