I didn't see a thread for this yet so thought I'd get it started. Card: AA Citi Amex How long card was open: About 6 months Spend: I spent maybe a few thousand on the card over the 6 months I opened an AA Citi Amex about 6 months ago to get a 20k sign-up bonus. Tried to cancel the card last month and was offered 3k miles for spending $500. Normally I'd only keep it for 5000 or more, but I went ahead and kept it. The next day, I bought a few gift cards (about $800 worth). My 3000 bonus points posted + my 800 miles + another 400 miles (listed as bonus on my statement). The CSR didn't say anything about additional miles above & beyond the 3000, but it seems I'm getting some additional bonus (50% of what I spend). So I'm going to try to use it a little heavier this month to see if I can pick-up some extra bonus miles.
