call customer services and req a manager or above right away. I would say something like this " Hello my name is blah blah i purchased a ticket on last minute notice for "a family problem or business" (which ever it is). As a busy person I was trying to save time and use your helpful nwa.com check-in but was advised I would not be able to b/c i bought my ticket today, for travel tomorrow. It is very disappointing to learn that i will not be able to qualify for your highly advertised promo of the 2,000. Is there anything you could do to help reduce my disappointment with your nwa.com check in, it does not say that there could be times that it cannot be used the day be4.
They should credit you for the 2,000 bonus miles. Let us know what happens
