Somehow I missed this extension. Budget is offering 5,000 Delta SkyMiles for every 2 day car rental through May 31, 2010.
Delta SkyMiles members can earn 5,000 bonus miles and save up to 30% off on all qualifying rentals of 2 or more consecutive days at participating Budget airport locations in the U.S. and Canada.
Make sure you book with rental Coupon #MUAZ015
Delta is offering a 50% bonus on miles earned through car rentals through April 30th. This is a great way to rack up 7500 (5000 + 50% bonus) for every rental.
