If you’re planning to go home for Christmas, expect lots of company on the highways. Holiday travel is expected to set records this year, with 2.8 million people in Georgia and 98.6 million across the country projected to travel 50 or more miles during the year-end holiday season, according to AAA. That’s a 4.6 percent increase in the state and 4 percent nationally. “Continued growth in consumer confidence and disposable income, an extended holiday period, and low gas prices should drive expected travel volumes to the highest level we have ever seen during the year-end holidays,” said AAA spokesman Mark Jenkins.
