now and improved offer of 35000 miles after spending $750 in 4 months (remember, you can buy US Mint coins!!!!) - no annual fee for first year. LINK
The most common cards have always been the co-branded Mastercards. That’s what most people have or have had. Citibank isn’t as generous with allowing people to get the same signup bonus over and over any longer. But if you haven’t had these other cards, you should be able to get signup bonuses for them even if you’ve had Mastercard products in the past. And this represents as much as 105,000 bonus miles.
I highly suggest getting these cards - 35000 x 3 - 105K AA miles - that's 2 tickets to Europe, multiple domestic or Caribbean tickets....the list goes on...what are you waiting for...
