Updating my credit cards

[Anonymous]

Hi everyone,
Looking to totally update my credit cards.
I have an Amex platinum, diners club, chase united mileage , and a discover.
I have a fico of 804 and I'm looking to something to benefit travel but also want to gain miles for travel.
Which cards would you ditch and which ones would you keep?

I would recommend getting the CSR. 3X travel and dining. $300 yearly travel credit. Priority Pass. Travel insurance etc...I would get rid of the United and the Amex Platinum if you don't want the perks that come with it like Centurion Lounges. Otherwise a lot of the benefits overlap and the 3X travel is better than you can get with United.

Thanks for the reply. I always enjoy Amex and I do like the Uber credit plus the lounges. I would like to cancel the visa United card but (a) if it's one of my oldest cards, will it zap my Fico pretty hard (b) is there a downgrade card that doesn't have a 95 dollar annual fee. (C) if I cancel my United chase visa but open another chase card, will I lose my 380,000 miles because it's not a "United mileage " card?

thanks
