Once again, I"d have to math the situation out.
Current Math: $450 AF on CSR minus $300 travel credit I am spending anyway = $150. Difference between $150 CSR - $95 CIP/CSP = $55.
Possible future math: $550 on CSR minus travel credit I am spending anyway - $250. DIfference between #250 CSR - $95 CIP/CSP = $155
I"d still keep it. We booked 4 nights at Ashford Castle with UR points for next year. All in the price of the hotel was $4,117. We "paid" 274,477 UR points through the CSR. If I had a CSP/CIP I would have had to pay 329,372 UR points. That's a difference of 54,895 points. That's a $548 statement credit, CSP/CIP value of $686 or CSR value of $823. For the way I redeem points via UR it is still more vaulable for me to keep the card even if they raise the fee for something I can't or won't use. PCing the card would cost me too much money lost in point redemption.
I get that not everyone goes through and redeems points the way we do. But even those doing once a year redemptions may want to look at their own mat before jumping the gun one way or the other.
Let's say you are going to redeem a $500 RT flight for a party of 2. That's $1000. If you hold a CSP or CIP that should cost you 80,000 UR points. If you hold a CSR those flights would cost you 66,666 points. That is a difference of 13,334 points which is equivalent to $166 in the CSP/CIP UR portal. So holding the CIP/CSP over the CSR just cost you $166 in points. If someone is redeeming $1,000 or more via the UR portal each year, then they may be looking at a small loss, or in my case a huge loss by PCing the card if it goes up to $550.
