This is my primary card for all purchases, earning 2.625%. This is the best no fee card and the payout is better than several fee-only cards. I and my SO have several cards (SPG personal, Citi AA, Aviator) on which AF will be hitting soon; The AF on my SPG business just hit yesterday. I paid AF on Ink+. I don't plan to apply for cards for a while. Are there any reasons for keeping the AF cards?
