To OP's question:
Mattress run on AA hotels or some eShopping would be easiest best to secure the LP's. You can view eShopping merchants and sort by earn rate to see where you can get the best bang for your buck.
That coupled with the base miles from AA CC spend should hopefully get you there.

I've never had Citi or AX care, keeping in mind I pay off the balance in full each month regardless. I've never done an analysis to see if all of this spend exceeds what is my credit limit in a given month, so it's possible I just never ran into some sort of T&C that others have.
Citi is looking a more recognizable pattern of cycling, perhaps with purchases from a small group of merchants, or merchants with higher risk factors (i.e. MS activities) that are repetitive monthly or in $$$ amount.
Similar to USFlyerUS, I had a 4 month or so stretch where I was expensing alot of work stuff om personal CC to get miles. Probably a half dozen or so merchants mixed in during the period, and cycled the CL 1-2x per month for a few months. Nary an issue there.
