Frequent flyer program (in part): The Company utilizes a number of estimates in accounting for its WorldPerks frequent flyer program. The company accounts for the frequent flyer program obligations by recording a liability for the estimated incremental cost of flight rewards expected to be redeemed on Northwest and other airline partners. Customers are expected to redeem their mileage, and a liability is recorded, when their accounts accumulate the minimum number of miles needed to obtain one flight reward. The number of estimated travel awards outstanding and expected to be redeemed at December 31, 2006, 2005, and 2004 was approximately 3.6, 3.6, and 3.8 million, respectively.
