I received a postcard from the AA/Kelloggs fulfillment center back in November or so, saying that effective 1/1/02 coupons could not be submitted in increments greater than 1,000 miles at a time, that additional coupons would not be returned, that expired coupons would not be accepted or returned, and a maximum number of miles (200,000) could be redeemed from 1/1/02-1/31/03 through this promotion.
(Edited to update maximum number of miles and time limit to submit them.)
