Since a few of you were interested in my "slow churn/no churn" approach, I thought I would outline a little more about my CC rewards journey.
Prior to 2016 I had more than a few CC, but primarily had the Amex Everyday (my oldest card- 1980's) and Disney Chase (acquired in 2009). I used neither regularly. In 2016 I decided to explore the CC "rewards for travel game." Here is how I evolved to the five/six cards I use now:
-Had Amex Everyday
-Had Chase Disney (usually in sock drawer these days unless planning a trip or have a promo)
-3/2016 - CSP - this is the only AF card I currently hold; pay the AF with Discover IT cash back
-7/2016 - CF - recently PC'd to CFF
-1/2018 - Discover IT
-8/2018 P2 gets Chase United - since PC'd to the no fee version and now in sock drawer. Keeping it only for the expanded choices for reward travel should we eventually use United for international travel. I use this card once or twice a year just so it won't get closed.
-7/2019 - P2 gets CFU.
-Somewhere in there I also had a Chase SW and a SW Premier - both since closed.
-Somewhere in there P2 had the CSP for a year - since closed.
Out of all of this, the cards I use regularly are the Amex Everyday, CFU, CFF, CSP, and Discover IT. I use whatever card gets me the most back for each individual purchase.
I only use the rewards for travel related expenses (so no PYB unless I am buying a travel-related gift card.)
I do not MS or buy stuff just for the points. I put just about everything on CC (DH not so much) and pay off weekly or more than weekly, so they essentially act as debit cards.
I do not pay anything with a CC that has a fee associated with it. I do not pay anything with a CC that cannot be directly paid with a CC (so no Plastiq, MOs, or buying GCs for future spend).
We travel roughly once or twice a year. I have paid very little to no OOP since earning the subs on my first few cards. I also am able to fly my college child home and back several times a year using points.
We have all said it before: There are many ways to play the game. Don't be afraid to get your feet wet and try it out, slowly. You can always speed things up if you find this hobby is for you. And if you find it is not for you, all cards can be cancelled whenever you like.
ETA: If (when?) I burn through the points I have, I am not opposed to churning the CSP or adding another card with a good SUB. But until that happens, I am happy with the cards I have. I don't feel I need to keep accumulating points by getting more cards. For me this is easier than always having an MSR for a SUB and keeping track of multiple cards.
