Delta rewards it's flyers for flying with them. Companies reward their customers by offering them frequent flyer miles for buying their products. In each case, the flyer or the consumer purchasing products redeem their miles for a free reward. In this case, there is no difference between the flyer and the consumer. Delta does, and I emphasize does, receive revenue from each source. As long as airlines are going to offer frequent flyer miles as an incentive, why should non flyer miles be considered any different as long as their account remains active?
