It seems like Citi offers like 6 or 7 different AA cards? Why so many? I've gotten the AA Amex, the Visa and the Mastercard versions allowing me to collect huge signup bonuses for each card. I've taken those miles and used them for a free flight to FL from Europe! 80K miles of so for doing absolutely nothing.If I had a business, I'd be able to fly to the moon for free! Why does Citi offer so many AA cards, offering sign-up bonuses to first time card holders for each different card? It's almost too good to be true!
