BML doesn't report, so other creditors just see the HP and not the tradeline. No reason to close it other then if you can't control yourself with the spending hehe.
Does the NYC have an AF? If not, then just keep it open so it can grow in limit and age.
No it doesn't but at the same it's not going to be used... I don't want it to be closed by them and I'm trying to get rid of lower limit cards :/
