Polaris Club Lounge access?
Hi,
UA Premier Silver Mileage Plus Member here with UA Club lounge membership. I'm flying tomorrow to Mexico on business, connecting in Houston, and I've been upgraded for free to United First on the 1st leg and United Business on the 2nd leg.
Does the upgrade to First/Business class give me access to the Polaris lounge? Or does it have to be a paid First/Business class ticket?
