Going out of town this Fourth of July weekend? Be prepared for a record-breaking amount of company.

Nationwide, 42.9 million people are expected to travel during the holiday weekend, up 1.3 percent from the record high that was set in 2007 and tied last year, according to the Auto Club.

The travel frenzy is being fueled by lower gas prices, as well as a growth in consumer confidence, Filomena Andre, AAA’s vice president for travel products and services, said in a statement.

Travelers could still run into long lines at airport security.

In the spring, the Transportation Security Administration was heavily criticized over lengthy screening lines at airports that caused thousands of travelers to miss their flights. This month, the head of the TSA said significant progress had been made on shortening waits by adding lines and staff.

Government officials have been urging travelers to sign up for TSA PreCheck, which allows fliers to use an expedited screening line if they first submit to a government background check. But the program has become inundated with applications, and it can take weeks to get an appointment to enroll.
