Update:
I was approved for both the Personal VISA & AMEX 75,000 mile cards instantly online last night, but am awaiting approval for the 75,000 VISA BUSINESS cc.
I called them today to verify the AA Advantage bonus terms on both cards and while I thought I signed up for 1 of them w/the $1,500 spending required and 1 of them with the $4,000 spending required - - I was informed that they are both $4,000 required to spend within first 6 months. She did say that I WOULD earn 75,000 miles for EACH card though, for a total of 150,000 miles! AMAZING!
Now I just have to make sure I have funds available for all these transactions and we are golden.
