Receive discounts automatically with reservations produced on the ABA Orbitz for Enterprise booking web-site. A different perk: Military personnel on Rest and Recuperation (R&R) leave from any operation with military leave orders have access to United Clubs (have your military ID and a copy of the orders or leave authorization for entrance). As an icing on the cake, we even offer you final minute flight offers for you so that your holiday just gets better. We will only accept authorized, U.S. government-issued Visa and MasterCard accounts as payment, and only staff of the federal government traveling on official small business are eligible for these fares. Discounts may vary or be unavailable depending on the time and date of a flight.
