But did you cancel both the card account and the master account associated with it
??? 
You don't mention
anything about cancellation.
The business AA card can only be churned if you fully cancel (both the card account and the master account of) the previous card
before you apply for the new one. That's explained in the wikipost above.
(And that's completely different than the cancellation rules for Citi
personal cards, which are that you don't need to cancel before apply for another.)
