Tens of millions of Americans plan to travel this Fourth of July, but it may cost them a bit more than last year to get where they’re going. AAA predicted last Thursday that 40.8 million Americans will travel at least 50 miles from home over July 4, traditionally the most traveled holiday of the summer. That’s a 0.8 percent dip from last year but still higher than the 13-year average of 38.9 million Americans who celebrate Independence Day by getting out of town. Since the holiday falls on a Thursday, travel is likely to be down slightly compared with 2012 because of a shorter travel window, AAA says. The continuing fallout from budget cuts by the federal government may also keep more Americans at home.
