AAA: More traffic this Memorial Day weekend

Slightly more travelers are expected to drive to their getaway destinations this Memorial Day holiday weekend, AAA reports.

While 31.2 million people will drive during the holiday, up 0.25% from last year, only 2.3 million will take leisure flights, down 7%. Reason: higher air fares and relatively stable, but still high, gas prices.

Gas prices average $3.66 a gallon Wednesday, down 2 cents from the same week last year, AAA reports.

While the economy has improved in the past year, AAA CEO Robert Darbelnet says the end of payroll tax relief could hold back travel. People are expected to spend $659 over the weekend, down about 6%.

The average journey over the weekend will be 690 miles, higher than last year's 642 miles.
