I have a United Mileage Plus card which I've had since 1987 with a credit limit of 25k. My total credit limit is 154k. My credit Karma score is 773. I'm sick of watching everyone getting 60k bonus miles offers while I'm getting nothing for being loyal. My question is how much of a hit on my credit score am I likely to get if I cancelled the card and when can I apply for the new explorer card after cancellation. Also, How long is it gonna take for my score to build back up? My $85 annual fee is due in Feb. Any advice?
