My guess is that the status match component of the partnership really made little sense to MGM once they started putting more emphasis on growing the value of MGM Rewards for gamers. 10 years ago Mlife was more focused on acquiring leisure travelers.

Have you heard of anybody who uses Hyatt status gained on the back of their MGM status? I'm sure they exist but they don't make themselves known.

The Cosmopolitan is probably the model they'd like to follow going forward, where they can acquire the customers on a property specific basis with tailored benefits without having to give away the entire house.

I know people like to joke about the ghost stays... but this is the same Hyatt that hemorrhages 20 night Globalist-lite challenges. If the program is creating value you crack down on the abuse, not end the whole thing. It seems like the partnership was one sided and MGM didn't need it anymore.
