<prompt> Human: I have a JetBlue Card from American Express. From what I understand it isnt even a credit card but rather a charge card which doesnt even help me build my credit.I dont think I can do a product change to a different Amex card because the JetBlue card is kind of its own separate thing. I want to get a new credit card, but I want to get rid of this one first, and I dont want to hurt my credit or my financial standing.Do you have any advice? Thank you!  <response>: When cards expire the company just sends you a new one with a new expiration date. The expiration is for the card, not for the account.Letting the card sit and not use it will result in it eventually getting closed if youre talking about free accounts. For cards with an annual fee, however, Id expect them not to use this practice. Just call and cancel the card. Its not a big impact.
