Im about to close my CSR dont think its worth for me the $450 annual fee (i did already the $300 travel spend for 2018)
Whats my best option to do not to lose my credit limit, The only other chase card i have is the chase freedom,
Should i just move my CSR credit line to the freedom i have, or should i downgrade it to the freedom unlimited or free sapphire version?
Only you know how you spend your money, what benefits are important to you etc.
If you're closing your CSR, then you'll have no cards to transfer UR to airline or for the bonus kicker on UR redeemed on Chase Travel. Which means your Chase cards will all be cashback To me, that would make an FU worthless since it would essentially be a 1.5% cashback card which can easily be beat. Under those assumptions, I would product change the CSR to a 2nd F5. I would also transfer all but $2K of the credit limit to the older of the 2 accounts.
