Meanwhile, on the other end of the churning strategy spectrum ...
Sometimes it makes sense to pay the AF if the benefits are valuable to you. I don't keep all of the cards I open but I do keep a lot of AF cards because the benefits outweigh the fee and are easily redeemed for us. I also have a bunch of AF cards that sit in a drawer and will continue to sit in a drawer because they offer me no value with spending. Examples of those would be:
Club Carlson - 40k Radisson Rewards points each year. DH and I each have the card and we let the points pile up until we need them for a stay in Europe. The value of those points for each stay has been far more than both of our AFs year after year.
Chase Marriott/Bonvoy personal and Amex business Bonvoy and AMex Brilliant Bonvoy - DH and I have one one of each and easily use the 4 free night certs for weekend getaways and can do the same with the credit on the Brilliant card. We've always redeemed the free nights for tays that would cost more than the AFs with no problems.
IHG - free annual night at any property which for us ends this year. We have one more each to use. Then it will be capped at 40K properties. I still think this will be an easy free night to redeem moving forward so I'll keep it.
Amex Hilton Aspire - I love the benefits of this high AF card so much that we are each working towards getting a second one. A free weekend night at any Hilton property is worth way more than the AF especially when combined with the $200 resort credit and $250 airline credit.
CSR and Ink+ - These are the foundation of our UR earning and without them I would not be able to earn as many UR ongoing as I do.
Amex Gold - the dining credit and airline credit make this card's AF negligible and the 4x categories on dining and groceries really help beef up the MR stash which we use quite a bit
Amex Plat personal and business - Dh may or may not be keeping the business card and I'll be keeping the personal card when the AF is due. I will be cancelling my business plat card. We do use the benefits offered by each enough that we might be keeping one of each but both of us don't need to have each. So, they will be re-evaluated in a few months.
I understand this. There's no way DH will give up his amex platinum at this point. He travels so much it makes perfect sense for him.
