So, this is a question that I'm curious about.
I have an Puerto Rican BPPR AA Visa, and now a USA Barclays Aviator Card. On top of this, I'm going to apply for a USA Citi AA MC (waiting for a good bonus).
Is there any risk on my open accounts, or my AAdvantage account to have multiple cards from different issuers?
No, many do so. I just recently applied for the US Barclays, and currently have the Citi Executive card, the one with Club access.
