I called the amex customer service line and asked if I could combine accounts. They said no because they ate two different products. The gold delta sky miles and blue sky. That's fine, my next question was can I reallocate the limit from one card to another. They said I could so my next question was will it be a hard pull, soft pull, or no pull at all. The csr said he could not tell me. No matter how I asked he could not tell me whether or not they would pull my credit. Does anyone know if they will? I'm leaving 500 on one card so not closing it. Planning on a mortgage so I want to keep my scores intact,.
