One additional credit per one-way flight will be issued regardless of fare purchased.  Members must register for this promotion between Sept. 17 and Oct. 31, 2009, to qualify and registration must be completed prior to commencement of travel.  Reservations must be booked between Sept. 17 and Oct. 31, 2009.  Travel must be completed between Sept. 17 and Oct. 31, 2009.  The Rapid Rewards Award is free, but travel is subject to the government-imposed September 11th Security Fee of up to $10 per roundtrip.
