Manufactured Spend, MS, is a term I only learned from reading on FT. I still don't know what people do with MS. I have never even churned CC for sign up bonus. I only applied for CC that I find value in their points in the past 30 years, such as SPG AMEX (before sign up bonus was even offered), Hyatt Chase Visa (2 free night certs) and WoH Chase Visa (60K points bonus), and CSP (80K bonus bonus). I haven't yet transferred any Chase UR points to Hyatt.
I earn WoH Globalist status and points the old fashioned way, by staying at Hyatt hotels and spend on WoH Chase CC.
