The U.S. Thanksgiving holiday is fast approaching and that likely means busy meeting and event planners can take a day or two to relax. However, there may be some added stress if you have to drive (or fly) somewhere.

AAA projected 50.9 million Americans will journey 50 miles or more away from home this Thanksgiving, a 3.3 percent increase over last year. The 2017 holiday weekend will see the highest Thanksgiving travel volume since 2005 with 1.6 million more people taking to the nation’s roads, skies, rails and waterways compared with last year. AAA and INRIX, a transportation analytics company, predicted that travel times in the most congested cities in the U.S. during the holiday week could be up to three times longer than the optimal trip.

“Thanksgiving kicks off the start of a busy holiday season, and more thankful Americans will travel to spend time with friends and family this year,” said Bill Sutherland, AAA senior vice president, travel and publishing. “A strong economy and labor market are generating rising incomes and higher consumer confidence, fueling a strong year for the travel industry, which will continue into the holiday season.”

The Thanksgiving holiday travel period is defined as Wednesday, Nov. 22 to Sunday, Nov. 26.

By the Numbers: 2017 Thanksgiving Travel Forecast

  • Road trip ready: 89 percent of all travelers—45.5 million—are planning a Thanksgiving road trip, an increase of 3.2 percent over last year.
  • Cheaper airfare: Consumers will pay the cheapest average airfare since 2013.
  • Fuller skies: The largest growth in holiday travel is by air travel, at five percent, with 3.95 million travelers.
  • Alternate travel: Travel by trains and other modes (including buses and cruises) is expected to increase 1.1 percent to 1.48 million travelers.
  • Fueling up: Drivers will pay the highest Thanksgiving gas prices since 2014.
  • Holiday high: Car rental daily rates will hit a five-year holiday high at $70/day, which may be due to an increase in domestic demand and cost of newer vehicles.

Travelers still hitting the road despite higher gas prices
While AAA expects most U.S. drivers will pay the highest Thanksgiving gas prices since 2014, the vast majority of holiday travelers (89.3 percent) are still planning to hit the road. Automobile travel will grow by 3.2 percent this Thanksgiving, with 45.5 million Americans planning a holiday road trip. This November’s national average gas price is $2.54, which is 37 cents more than the national average recorded last November (1st-14th).

Travelers Beware and Advised: Traffic Hotspots and Best and Worst Times to Hit the Road

Based on historical and recent travel trends for the holiday week, INRIX, in collaboration with AAA, predicts drivers will experience the greatest amount of congestion during the early evening—as early as Tuesday of Thanksgiving week—as commuters mix with holiday travelers. At its peak, drivers on Chicago’s interstates, for example, could see a delay of nearly 300 percent over the optimal trip, according to INRIX and AAA.
