If airports seem more crowded these days, they should. About 6.3 billion passengers passed through the world's airports in 2013, a 4.6% increase from the previous year, according to an Airports Council International report.
Atlanta's Hartfield-Jackson Airport (ATL) reigns as the world's busiest airport by passengers in the ACI report even though its traffic dropped 1.1% this year over last. Still, the 94 million-plus passengers last year kept it in the top spot.
