I have several Chase cards that I'm not using (we have three UR cards that we do use). I don't anticipate putting any spending on these cards, unless I can decipher the threads in the Manufactured Spending section and figure something out, but I did wonder whether I might be able to transfer these accounts to other Chase rewards programs and take advantage of any signup bonuses. Is this possible, and, if so, what's the best way to do this? Cancel and reapply, or call Chase?
