Atlanta's airport once again emerges busiest in the world

Once again, Atlanta's Hartsfield Jackson International Airport has emerged the busiest airport in the world.

Hartsfield Jackson retains the top spot from last year welcoming over 100 million passengers in 2015, a rise of 5.5% over 2014.

This is according to preliminary traffic data released by Airports Council International (ACI) which credits Atlanta's strategic location as a major connecting hub and port of entry into North America for its continuing success.

According to the report, Atlanta is a two-hour flight of 80% of the United States population and has held the top spot for 18 years.

Beijing's airport came a close second and was expected to beat Hartsfield Jackson this year, however the reports states that "the combination of a Chinese slowdown and capacity constraints has meant lower growth levels at the airport."

Dubai International Airport emerged the world's busiest in terms of international passengers, ahead of London Heathrow.

Also, the world's largest air cargo hub remained Hong Kong.
