U.S. gas prices at Thanksgiving are highest since 2012

As an estimated 48.3 million Americans hit the road for Thanksgiving, they're going to find that gasoline prices along their route are not to their liking.

Thanks to inflation, the holiday meal at their destination will be expensive to put together, and getting there will be a bit higher too. According to AAA, the national average for a gallon of unleaded gasoline is $3.40, the highest it's been for the Thanksgiving holiday weekend since 2012.

In an era where more cars are turbocharged and require premium, the national average price for higher-octane fuel is $4.03.

Diesel's national average is $3.64.

California has some of the highest averages, with regular at $4.70 a gallon and premium at a hair over $5.
