Estimates from AAA say nearly 3.5 million people from Michigan will travel for the year-end holidays, up 2.5 percent from last year. The auto club says Thursday it’s the highest total volume of people going 50 miles or more from the state since AAA began tracking holiday travel data in 2001. Most will drive. AAA says the increase in holiday travel is being boosted by additional consumer spending, a result of improvements in the labor market and rising wages. Additionally, relatively low gas prices and increased consumer optimism are seen as factors. The year-end holiday travel period is defined as December 23 to January 2, one day fewer than last year’s holiday period. It includes Christmas, Hanukkah, and New Year’s Day.
