AAA forecasts that more than one-third of Americans and two-in-five Tennesseans will travel this holiday season. The record-breaking 112.5 million travelers taking to the nation?s runways, roads and rails for the year-end holidays is the most since AAA has been tracking holiday travel. That represents a 4.4 percent increase over last year nationwide and a 5.1% increase in travelers from Tennessee. The year-end holiday travel period is defined as Saturday, December 22 through Tuesday, January 1, 2019. The 11-day span is one day longer than last year, due to Christmas and New Year’s Day falling on Tuesdays this year.
