<prompt> Human: I have two cards right now: Citibank Gold AA Advantage: I have been with Citi for over 15 years, this is the first card I ever had. The current one is active since 2008 but I was a customer since about 2000 when I turned 18. I just paid off my entire balance. The interest rate is about 13 but the benefits of this card are basically nothing for American Airlines points. My credit limit is 12,500. JetBlue Amex: Customer since 2014. Balance is about 4K, interest rate is 15. I love this card because of the points, I fly JetBlue all the time and have taken many free trips with points. I have a 15K limit. About me: I make about 45K right now and have about 3K in savings. My only other expense right now is my car which is 400month if I include insurance. I have no other bills. Im about to be done with my MBA and hope to make more money after, but will also have to start paying student loans off. That is for another thread entirely though, not worried about that now. I have excellent credit. Score across the board is in the 750 range and my FICO score is close to 800. I have NEVER missed a payment in 15 years of having a credit card. Question:Should I keep the Citi card open since it has such a long history to it and now I have a 0 balance? I plan on just using the Amex and maybe keeping the Citi card open for emergencies...should I consider canceling the Citi card and getting another one with good perks or keep it since its at 0 and Ive had it open for so long? Thanks!  <response>: I wouldnt cancel the Citi card because it is such an old account which is one thing that affects your credit score the older an account the better.I would call up Citi and inquire about switching your AA Advantage into another Citi card, possibly the double cash which is a great card because you get 2 cash back on everything. When you call them up say you would like to do a product change, not close the card. This would keep the history of the account intact.
