American's domestic deal competes with Southwest's systemwide sale as well as offers from other airlines, so you'll have to compare prices before you book.
Book your Hertz car rental for the weekend online, and get 50% off the regular rate. This offer is available for economy through full-size vehicle rentals. Just book a minimum 2 day rental and travel by June 30, 2008.
Spirit's sale fares are available through Sunday at 11:59 p.m. ET. You'll have to move quickly to take advantage of these prices, which are some of the best you're likely to find for travel to Latin America.
Southwest's new deal ends on Monday, March 31, at midnight CT. This deal includes a few competitive prices, but you should still shop around before booking.
United's new deal features flights between Reno and Chicago, Orlando, New York, and more. But United's everyday fares beat many of the sale prices included in this offer.
