I'm new here posting for the first time. I'm trying to figure out if I should eliminate some of my credit cards. I have the following:
AmEx Platinum
Delta Reserve
AmEx Starwood
Corporate Am Ex
Chase BA
Chase United
Citi AA

I only travel for business occassionally. I make 3 or 4 trips to Europe a year, one of which is usually an award ticket.
I shop alot.

I am currently Delta Gold. I got the DL Reserve to get the MQMs and make Gold this year up from Silver.
I have the Platinum because I like having the rewards that can transfer to various programs and the fact that it gives me Starwood Gold.
I like Starwood for the points and cash award and I generally get upgraded because of the gold status.

I'm thinking of getting rid of the Chase BA card because the surcharges for awards make them unattractive to me.

Any suggestions for an additional card keeping in mind that most of my points will come from shopping and not from hotel stays or flying (other than my trips to Europe which are generally on DL/AF/KLM.

Suggestions appreciated. Thank you.
