Applied online, but after submitting my app, I got a msg that basically said: call us, but you're pretty much approved. Next day, I called & only had to verify my address, then 2 mins later: "You're approved for a $8,500 LOC," but it's a Flexible spending acct. The standard APR is 15.24%, all day every day - for this card and all other Citi-AA cards. (My mom has Citi AA Plat MC and Citi AA Amex, which I've verified have the same apr.)
Also, only pulled EX, which had a 728 plus score, and no negative accts. I was declined for this card in '09 w/ 682 score and one neg acct.
A big plus about this card is that Citi reports your acct to CBs within a couple days of approving app- like, my CRs showed this acct before I even got the card in the mail, which only took 4-5 days. Very happy w/ this card and the 30,000 bonus AA miles!
My opinion based on personal experience and if I am reading correctly you currently have two capital one credit cards that are both under a year old, with your secured card getting closer to one year...
