I tried to close one of my 3 AA Plat Visa cards and they offered me $95 statement credit and 1,000 mile bonus for $1,000 spend for the next 16 months. I was hoping to transfer the CL from the cancelled card to one that has a $2000 CL, but what is essentially double miles for 16 months (if I only spend the $1000/mo) was too good to pass up.
I will call to cancel another card in a few days and we'll see if I get the same offer. If VRs and BB work for the next 16 months, I'll be able to handle 5 such offers with ease, and I have 6 AA cards. Could be very interesting -- at a rate of $0.00395/mile, a trip to Asia in C would only cost me $474+fees.
