Gas prices heading into the Memorial Day weekend are at their lowest levels in nearly two decades. According to AAA, the national average gas price is just above $1.90 a gallon.

But on this unofficial start to the summer holiday season, that might not be enough to get people to hit the road.

AAA usually issues a Memorial Day travel forecast around this time, but this year the company said COVID-19 undermined the data it uses to make that prediction.

“It’s not necessarily reliable, right? There’s not much going on with the economy right now to give us good indicators of what we can expect for travel and the holiday weekend,” said Jeanette Casselano, AAA spokesperson.

Casselano says people will still travel, but overall, travel could fall to a record low for the weekend, despite cheap gas prices.

The bright side? “We’re nearly a dollar cheaper than a year ago, and we’re not going to jump back up to the typical summer numbers anytime soon,” Casselano said of gas prices.

Traffic has started picking up, though. Patrick De Haan at the price tracking company GasBuddy says that means demand for gas is rising, too.

“It’s still down 20% from where it was prior to coronavirus, but the rebound has caused gas prices to rebound as well,” De Haan said.

He says those prices will likely keep climbing through Labor Day.
