According to the latest report from the Montreal-based Airports Council International, passenger traffic to the Atlanta airport grew nearly six percent in 2015, shattering previously held travel records.

In addition to being the primary hub for Delta Air Lines, Hartsfield-Jackson benefits from its strategic location as a major connecting hub and port of entry into North America: The airport is within a two-hour flight of 80 percent of the US population.

It serves 150 US destinations and 75 international destinations in 50 countries and sees more than 250,000 flyers pass through its halls daily.
