Not that you need another reason to go to Las Vegas, but Northwest is dealing up a generous promotion to get you there with some miles left in your pocket. Award flights from the Midwest to Las Vegas have been discounted 5,000 miles until Dec. 10, for travel until Dec. 14. WorldPerks members can redeem 20,000 miles for a standard coach-class award, or 40,000 miles for a first-class award. Non-stop flights between the following cities to/from Las Vegas are eligible for this offer: Indianapolis; Des Moines, Iowa; Flint, Mich.; Grand Rapids, Mich.; Fargo, S.D.; Sioux Falls, S.D.; Milwaukee and Madison, Wisc. Award travel is limited and capacity controls do apply, so quit playing Internet poker and book your flight before all the good seats are full. Travel must be booked online at nwa.com or by calling 1-800-44PERKS. For more information or to book your award seat, visit http://www.nwa.com.
