So I have the Costco visa now and no longer want - It is about 4 years old and need history. I called Citi to product change 3 times and all 3 said would require new number. I want to product change to the Rewards card. I understand it to be since I am not getting the bonus, I will still be eligible for the Premier bonus when I apply sometime in the next 6 months?

Bonus ThankYou Points are not available if you received a new cardmember bonus for Citi Rewards+℠, Citi ThankYouŽ Preferred, Citi ThankYouŽ Premier/Citi Premier℠ or Citi PrestigeŽ, or if you have closed any of these cards, in the past 24 months.

I have not received bonus, and I have not closed any card within this family for 24 months - so I am good right?
