WorldPerks members can drive their way to a flight award when renting with National Car Rental. Register for the promotion and complete six qualifying rentals between now and March 10, 2008, and in addition to the standard miles earned, you will receive 25,000 bonus WorldPerks miles — enough for a domestic PerkSaver award ticket between the U.S. 49 (excludes Hawaii) and Canada.

Qualifying car rentals include rentals of three days or longer per rental, of a mid-size or larger vehicle at participating National locations. To register for the offer, visit http://insideflyerus.wpengine.com/link/?749
