If you are asking about points earning limits with the Starwood Amex, there aren't any that I am aware of. Transfers from Starwood to most FF programs are limited to 99,999 at one time--but that's a DAILY limit.
sorry i probably wouldn't cancel the aa business card because i have 2 employees that occasionally use it, and it's not that expensive for managing 3 different accounts. But the largest purchases are by me.
the reason i was asking about point transfers is that when i had a regular old aa card before the business card, there was a maximum number of miles you could transfer in a year unless you had status, and i think the max was like 50k.
