Hey guys, so my AA Visa and AA Amex (one of the last of the double browser trick) are coming up on the annual fee. I just received my Citi Exec card and I kind of want to keep one of those two for the 10% mile refund... which one should I keep? Or should I just cancel both and apply for a Mastercard version? Btw, in regards to citi cards do you all stick to your AoR? Such as, I just applied for my citi exec card, should i wait 7 days to apply for a different one or just fit it in my next AoR? Thanks!
