Apologies in advance, as I'm not trying to hijack this thread, but I am on the fence for applying and need some feedback.
I already have a few premium cards, so the benefits aren't important. I also am concerned that Capital One doesn't offer the same breadth of travel protections of Amex and Chase. However, the signup bonus is enticing.

Looking ahead to year 2, I would anticipate downgrading to the no-fee Venture card. Compared to the existing cards in my portfolio, the Venture seems to align best with the Citi Double Cash.

I know both have the ability to earn points and be transferred to airlines. However Citi requires either the Premier or Prestige, much like Chase requires either a CSR or CSP. I currently don't have any premium Citi cards, but was wondering if Citi allows customers to convert cashback to Thank You points and combine those points with existing Thank You points, once a customer gets a premium Citi card?

If I keep the Venture, it would replace my Citi Double Cash for everyday spend. If I decide to apply for a Citi Premier card next year, will Citi allow me to convert my DC cashback to Thank You points and combine with those Thank You points from the Premier?
