While at the grocery store this afternoon, I checked out the cereal aisle! Sure enough, the Kellogg's cereals listed had the American Airlines certificates on the boxes, but you have to send in TEN (10) certificates at a time to get 1,000 miles, and the expiration date is now January 31, 2003. It's a good deal if you would've bought the cereal anyway - especially if it's on sale and/or you have a coupon. I didn't see AA certificates on any of the Nutri-Grain products at this particular store.
