Product Change from Citi COSTCO card in certain scenario
General question: Citi will not allow you to "product change" your Citi COSTCO card to another Citi card. Correct? If yes, what happens if Citi, hypothetically, loses, the COSTCO contract, to, for example, Chase Mastercard. In such a scenario, will Citi allow a product change to another of their cards?
This is not an unrealistic scenario. You may recall that a few years ago, Amex lost the COSTCO contract to Citi Visa. Do you recall if at that time, Amex allowed product changes to other Amex cards?
