Thoughts on how I have this planned/set up?

End Game Plan/Setup

Dining

• *Amex Gold

Groceries

• *Amex Gold (only at supermarkets)
• Capital One Savor (for non supermarkets)

Gas (need help here)

• *Citi Custom Cash (only issue is will need to get another Citi card to access travel)
• Amex Blue Cash Everyday

Travel

• *Venture X
• *Amex Platinum
• *Insert Citi card here

Online spending (need help here)

• Amex Blue cash everyday

Catch All Card

• *Venture X

Anything with an “*” in front of it is a card I don’t currently have but am planning on getting. My only issues are in areas like gas and online spending. If I get the Citi custom cash for gas, then I would like to be able to have access to travel options which means I would have to get like a Citi Strata Premier. I’m also interested in the Chase ecosystem but not sure where it fits in for my plan. I would like to stick with Amex for both travel purposes and the dining benefits on the Gold. Any recommendations of what you use?
