Triple-A projects 41.9 million Americans will travel 50 miles or more from home this July 4th holiday. That's the most since 2007 and nearly a one percent increase from last year. The Independence Day holiday travel period begins on Wednesday, July 1 and ends on Sunday, July 5. Rising income, driven by a strong employment market, is prompting more Americans to take a holiday trip this year. Despite recent seasonal increases, gas prices remain well below year-ago levels, which has helped boost Americans’ disposable income.
