For the first time ever, more than 100 million Americans—that’s roughly one-in-three—will travel during the year-end holiday season, according data compiled by AAA.

The 100.5 million Americans expected to travel for the holidays—defined by AAA as traveling 50 miles or more from home—is a 1.4 increase over last year and the seventh year in a row of consistent growth in holiday travel.

“Rising incomes and low gas prices are helping to fill stockings this year, and more people than ever will choose to spend those savings on travel this year,” says AAA President and CEO Marshall Doney.

The majority of holiday travelers—more than 90%—will be doing their travel behind the wheel, which is perhaps unsurprising with average price of gas nationwide at $2.01, a 53 cent discount from this time last year. Airfare too has declined slightly, AAA reports, by about 6% from last year on the top 40 domestic flight routes, to a national average of $174 roundtrip.
