Factors which could cause impairment include, but are not limited to, (1) a decision to permanently remove flight equipment or other long-lived assets from operations, (2) significant changes in the estimated useful life, (3) significant changes in projected cash flows, (4) permanent and significant declines in fleet fair values and (5) changes to the regulatory environment. For long-lived assets held for sale, we discontinue depreciation and record impairment losses when the carrying amount of these assets is greater than the fair value less the cost to sell.</font><font style="font-family:inherit;font-size:10pt;"> </font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;text-indent:18px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">To determine whether impairments exist for aircraft used in operations, we group assets at the fleet-type level (the lowest level for which there are identifiable cash flows) and then estimate future cash flows based on projections of capacity, passenger mile yield, fuel costs, labor costs and other relevant factors. If an impairment occurs, the impairment loss recognized is the amount by which the aircraft's carrying amount exceeds its estimated fair value. We estimate aircraft fair values using published sources, appraisals and bids received from third parties, as available.</font><font style="font-family:inherit;font-size:10pt;"></font></div></div>

As of December 31, 2011, we had not materially modified any of our significant agreements. Our most significant contract to sell mileage credits relates to our co-brand credit card relationship with American Express. For additional information about this relationship, see Note 6. For contracts entered into prior to January 1, 2011 that have not been materially modified since January 1, 2011, we continue to use the residual method for revenue recognition and value only the mileage credits. Under the residual method, the portion of the revenue from the mileage component is deferred and recognized as passenger revenue when miles are redeemed and services are provided. The portion of the revenue received in excess of the fair value of mileage credits sold, the marketing component, is recognized in income as other revenue when the related marketing services are provided.
