This Labor Day weekend, with 38 million expected travelers, marks a 9% increase from last year, driven by lower gas prices ($3.21 per gallon) and cheaper domestic flights and hotels. AAA advises avoiding roads Friday noon to 8 p.m. and Monday 1 p.m. to 4 p.m., and recommends car maintenance and safe driving.
