Has anyone tried to cancel their Citibank/AA Business card (with 1st year annual fee waived) after receiving the 10,000 bonus miles? Were you offered more miles to stay on-board?

Not that I'm unhappy with my nice 10,000 mile bonus for free, but I am thinking about cancelling since I only got the card for the bonus.

Since many of you may ask how to get this offer, what to do, etc., I'm going to try to pre-empt with the link to the original thread .
