LAS VEGAS (AP) — AAA predicts about 1.6 percent more residents in mountain states will take trips this Memorial Day weekend compared with last year.

AAA expects about 2.5 million residents of Montana, Arizona, Colorado, Idaho, New Mexico, Nevada, Utah and Wyoming to travel at least 50 miles over the holiday, mostly by car.

The travel group's forecast released Monday shows the average mountain states family of four will spend $652 over the weekend and travel about 677 miles.

Nationwide, 34 million people are expected to travel at least 50 miles during the final weekend in May. That's an increase of 1.2 percent.

Memorial Day airfare is projected to be about 7 percent lower than in 2011, while hotel rates are expected to be up 8 percent.
