Through October 31, Citi had some of the most ridiculous sign-up bonuses we’ve ever seen on their American Airlines credit cards, offering 75,000-100,000 miles per card as a sign-up bonus. While the spend requirements for the 100,000 mile card were steep, the 75,000 mile card only required a couple thousand dollars of spend.
Anyway, the offer is more or less back. Citi is offering a 75,000 mile sign-up bonus on their American Airlines personal Visa card, American Airlines personal American Express card, and American Airlines business Visa card. Only $4,000 in spend within the first six months is required for each of the cards, and the first year annual fee is waived. You can find the links to all three applications here. The current offer is good through February of 2011.
