Right before graduating high school I opened a "student" type credit card. It is listed on my credit report as having been opened in May 2007. The next month, I applied for and got a Royal Caribbean Visa card as we were going on a cruise and I wanted to build some rewards. That was in June 2007. So according to the credit report my second line of credit is only one month younger than my first line. The first card is rarely used as it offers no benefits to me. They are now charging a $25 annual fee to keep it. If I were to cancel it how much would it affect my credit? My credit score is in the excellent range right now. Thanks!
