Busy day yesterday and Lucky beat me to the punch on this one — United has a new promotion, stackable with double elite qualifying miles (not to mention threshold bonuses), that will give you a progressively larger discount on a future flight based on the number of flights you take through the end of year. (Ticketing and travel must be between September 14 and December 31.)
