ATL has consistently been named the busiest airport in the world with more than 250,000 passengers and nearly 2,500 arrivals and departures each day. This represents an increase in traffic of over 2.6 percent over 2015. This may be due to the fact that the city is within a two-hour flight of about 80 percent of the population in the country. The airport is also exceptionally dog-friendly.
