To ensure that “Emerald Aisle” locations are providing vehicles with less than 20,000 miles, National Car Rental uses the Emerald Club Scorecard to specifically track a vehicle’s mileage.

Every month, National Car Rental’s “Emerald Aisle” locations compete against one another at 65 U.S. airports, focusing on customer service scores, car-class categories and mileage criteria, says National.

“For ‘road warriors,’ low-mileage rental cars are always a priority,” said Brad Carr, vice president for Enterprise Holdings, which owns and operates National, Enterprise and Alamo brands. “As a result, we carefully measure this critical aspect of airport car rental all year long, constantly stressing business travelers’ expectations while also holding our regional operators accountable for this key metric.”

National Car Rental managers can evaluate all “Emerald Aisle” results throughout the U.S. at any time. “They can cross-check both their own rankings and others,” said Carr, “making the internal competitive process highly visible, totally transparent and extremely healthy.”

The “Emerald Aisle” expedites the rental process for Emerald Club loyalty members by allowing them to bypass the service counter and pick up their car of choice.
