This post is part of a series that will detail verbatim my negotiations with credit card companies to squeeze every last point and cent out of my cards.

Last August, I opened both the Citi AAdvantage Visa and Citi AAdvantage Amex at the same time to earn 150,000 American Airlines miles. The Visa had a spending requirement of $1,500 within four months to unlock its 75,000-mile bonus. After hitting that bonus, I moved on to unlocking the Amex's bonus then on to other cards.
