Qualifying travel must occur after registration and be completed between February 6, 2005 and June 30, 2005. Qualifying travel must be on a paid published fare. Qualifying travel must be nonstop between Detroit (DTW) and Reagan National Airport (DCA), Dulles International Airport (IAD) or Baltimore International Airport (BWI) on Northwest Airlines flights 1-1999.
