I have been accumulating Citi ThankYou (TY) points (not a huge number) for a few years now. However, other than for unattractive offers to purchase consumer merchandise/products that I see advertised in my account, I am not sure what else these points are good for...practically. Can I convert/transfer TY points to hotel (HHonors, Hyatt) points or airline (UA) miles? Information on transfers is inconsistent, with HHonors' site, e.g., saying that TY points can be converted to HH points, and the Citi site indicating that TY points can only be transferred to another TY account, after which they must be used within 90 days. What's up with that?
