I don't know an upper limit on churning, as I'm relatively new to this too.

I don't know how deep the creditors will look into your file...you would think that with online instant approvals, the number of opened accounts isn't being considered. But I don't know. I just hope that they aren't keeling over when they see how many I have opened and cancelled.

1. Apply for a different Amex card every 3+ months.

3. After 6+ months, re-apply for the same card.

I hope it works for you as well as it has worked for us!
