I'm a Star Gold (UA PremEx) flying on my first Tango flight on Sunday from YYZ-YUL. I understand that there is no MLL in YYZ T3, so lounge access is out of the question there, but would I be able to access the MLL in Montreal on arrival? I've called both UAL and AC and neither have the slightest clue how lounge access for non-AC STAR Gold flying Tango is handled.
