National Car Rental | 19,870 followers on LinkedIn. Founded in 1947, National Car Rental is a premium, internationally recognized brand serving the daily rental needs of the frequent airport traveler throughout the world. With National, time-sensitive customers in the United States are able to quickly choose their own vehicles, based upon their advance reservation and requested car class, and then simply drive away from the airport. National – which launched the car rental industry’s first comprehensive frequent-renter program – further expedites the rental process for Emerald Club members by offering counter bypass as well as access to National’s “Emerald Aisle,” an exclusive section of the lot where members can select any vehicle as long as they reserve a mid-sized car.
