As bustling as airports already are, they’re about to get even more so, if analysts are correct.
Industry trade group Airlines for America estimates that 222 million passengers will fly on U.S. carriers between June 1 and August 31, 2015, surpassing the previous record set in 2007. Among those passengers will be an unheard-of 31 million people on international flights. This will push up the number of travelers passing through airports all over the world.
