Millions of Americans plan to travel this Fourth of July

According to AAA, a record-breaking 46.9 million Americans will travel 50 miles or more away from home this Fourth of July. That's an increase of more than 5% compared to last year.

It's also the highest number since AAA started tracking holiday travel 18-years-ago.

Because of the increase travel, INRIX, a global transportation analytics company, predicts travel times in the most congested cities in the U.S. could be twice as long as the normal trip, with Tuesday being the busiest day.

This year, theme parks and Europe top the list for travel destinations.
