"Premium partnership"
It's worth remembering that your expectations seem to be that of an alliance, and not the partnership they have running currently. All of these benefits have to be explicitly stated, rather than implied or assumed.
I assumed, as a OWE (before I had EY status), that I would be allowed access to a lounge in AUH on AB (marketed & operated). On several occasions I was told to go fish. That is petty!
