Declared Ch. 7 in 2004.
Everyone that keeps quoting "7 years" is underestimating how long a bankruptcy persists on your credit report. Per FRCA:
Consumer reporting agencies may not report outdated negative information. In most cases, a consumer reporting agency may not report negative information that is more than seven years old, or bankruptcies that are more than 10 years old.
No affinity card would approve me, even with a 700+ credit score and two on-time auto loans, as long as that record was on my CR. Specified reason: "Bankruptcy on file." As soon as it aged out in 2014 I was able to get a number of cards (SPG AMEX, IHG and MR Chase, US Barclay, AA Citi (2x), and CapOne Quicksilver).
Even the cards I was able to qualify for were low limit ($500 - $1000 unsecured), high interest, high annual fee until 2011, which is when the defaults from 2004 aged out but the bankruptcy was still present. Then I was able to get a few reasonable interest, low/no AF, low limit cards approved.
This is all irrelevant to OP, because if you are declaring bankruptcy then churning is not the hobby for you. Spend the next 7 - 10 years learning to manage finances well is the right hobby to enjoy.
