Thanks for sharing! I just recently got started signing up for credit cards for bonuses and a little MS to meet the minimum spends quickly, so I'm sure I'm making mistakes here and there and have a lot to learn.
I just got my first Chase card last month (Ink Plus), although I'm an AU on a couple of my wife's cards. I have also had checking/savings accounts with Chase for 10+ years. I'm thinking they will auto-approve one and will verify that I have an existing relationship with Chase and the other will get approved fairly quickly. Of course, when I called the automated status line I got the message that the Chase signup wiki suggests often results in denials, so who knows.
