First, I would say the title to your thread is a little dramatic for a question about whether you can get into a lounge. Second, you need to be clear on what you're using to enter the UA club. My suggestion either way is to go to the club, and either you'll get in or you won't. If you don't get in, perhaps you can go find a nice restaurant in the terminal and have a beverage and a snack for a few bucks.
