I just got the Citi AAdvantage cards this week. Apply for both the personal Visa AND the personal Amex at the same time (using a second internet browser, so the cookies don't get confused). You'll get 2 cards, 75K x 2 = 150K miles, and best of all...it will only count as ONE credit inquiry if done at the same time (ie, on the same day).
If the Citi biz Amex card deal is still there, you can come back in 61 days and apply for that card, and get another 75K miles. But if you apply for all three at once, you'll get denied on some of them for not being a first time user.
