Would it be useful to put together all of our current information about the best / most effective way to churn credit cards, especially after the changes to Citibank's system? I picked them specifically because they have, at least recently, had the highest quantity and quality of credit card offers, with American Airlines. Here's my limited understanding of how to go about churning their cards in 2011. 1. You can apply for 2 credit cards in the same day, 2 personal or 1 personal and 1 business. However, you can also just apply for the 2 personal, wait 60 days, and then apply for the 1 business. This is a good way to get 3 cards in the time it would usually take to get 3. You do not need to actually own a business to apply for a business card, but there is a moral issue attached to this that you should decide for yourself. 2. You can reach the minimum spend for the reward as quickly as you like (for example, $4,000 in 6 months for 75,000 miles) however the points will typically be applied to your account 7 or so days after the billing cycle in which you reach the minimum spend target. 3. You can re-apply for 2 more cards 60 (or is it 90?) days after your last application date. Do you need to cancel the old cards to get 2 more? 4. You can safely expect a 4 - 6 point hit in your credit score each time you do this, however it is temporary and will go away after a 3 month period. If there is anything I am missing, or not giving enough detail on, please correct me and I will update this post. I'd like to clear the air on this subject, for my own sake, as well as for others looking to get these credit card bonuses. Thanks in advance! Copypasta directly from the FT thread about app rules - Generally: (as in most cases, but not a sure thing) 1. You can get approved for 1 personal card and 1 business card simultaneously. 2. If you want to apply for 2 personal cards, apply at the same time (same day at least). No promises on approval of a second card, but denial will not be because of your first application. For the 75k/$1500 promo, call in to apply for AMEX and then apply online for Visa. 3. Approval for 3 cards (2 pers. and 1 bus.) will certainly result in 1 denial. But accidental glitches can happen to get multiple cards. Even a few reports of people hitting submit multiple times by accident for the same card and getting approved for every submittal. 4. Applying for a personal and business card simultaneously will still result in 2 credit pulls. Applying for 2 personals will result in 2 credit pulls, but will be combined by the credit bureau into 1 pull. 5. You DO NOT need a business to apply for the business card, but this topic is ethics related. You do not need an EIN, just supply your SS # 6. If you have applied and did not get instant approval, "call us between the hours of 9:00 am to 9:00 pm EST, Monday - Friday, 1-866-606-2961" 7. Your application is not denied until they tell you it is denied, and even then there have been instances of applicants receiving the cards and activating them. 8. If denied for reasons other than "only for first time cardholders", you can contact Citi through mail or phone and ask them to reconsider or negotiate your approval. If lower level CSRs can't help you, contact the following: CitiBank Executive Review Department P.O. Box 6000 Sioux Falls, SD 57117 9. Some applications have no mention of the offer you are applying for, have faith it is correct. if you lack faith, you can confirm with a CSR after you apply using the above number. 10. If you receive a card and card info in the mail, it also will not have any mention of the offer you applied under, have faith or call a CSR. 11. Takes about a week to get your card. 12. Takes a few days after statement close to get your miles. 13. If you have been a churner, odds are a denial due to "first-time customers only". 14. If you have had an AA card long term (18 months to be safe) without churning, reports are you'll get approved. 15. You alone can evaluate if the risk of getting a denial is worth the miles. If you can't afford the credit pull, then don't worry about it.
