Recieved an email titled
Introducing Our Preferred Partnership With KrisFlyer from Marriott a few hours ago. In essence:- Direct match MR Gold -> KrisFlyer SIlver
Upgrade to KrisFlyer Gold was:
Upgrade for 12 months with just four flights on Singapore Airlines within six months of linking accounts. View your KrisFlyer statement to track your flight history.
Tried searching for an existing thread so if I missed something I deeply apologize.
This is the site Marriott linked to for matching, despite me being US English.
