According to Hertz, more corporate customers will rent cars in the U.S. during October than any other month of the year, driving an estimated 114 million miles.

With many business trips scheduled around summer vacations or delayed for after the start of the school year, October kicks off a busy stretch of conferences and conventions across the U.S. Combined with the fact that it is the last full month of working days before the holiday season, October becomes the month to hit the road for business, according to Hertz.

In October, Hertz’s U.S. Gold Plus Rewards members are expected to accumulate an estimated 350 million points and earn approximately 600,000 free rental days. To reward members with more free rental days, Gold Plus Rewards members in the U.S. and Canada can earn 550 bonus points when they rent twice from Hertz before Nov. 13 and register at HertzFallRewards.com.

"Hertz has been a leader in serving business travelers for nearly 100 years, so we have learned a lot about what's important to them," says Bob Stuart, executive vice president of global sales. "First and foremost, they want speed and efficiency. Delivering a fast and seamless rental experience is our top priority, especially during this peak time."

The top five busiest locations for Hertz in October are projected to be San Francisco, Los Angeles, Atlanta, Dallas, and Chicago. Monday is expected to be the peak day of the week for business travel, according to the company.

The research for October was compiled by Hertz and reflects its U.S. historical rental data from October 1-31, 2015.
