I applied and was given 1 AA MasterCard 75k miles card in September 2010. I applied at the same time for a 75k Visa but was denied based on the fact that I was already a citicard holder (from the MasterCard).

Is it too early to apply for another 75k card from Citi? What else should be my next few cards to apply to? I have great credit so approval shouldn't be an issue.

Thanks in advance.
