It's a rookie question because the last time I flew UA was in 2004, and before that in 1989. I will be flying them next week from EWR-AUS RT. So the question: I did a search, couldn't find an answer, can I use UA miles to "purchase" a Day Pass to a UA Lounge? I'm thinking not, because I also searched the UA website and found no mention of such. Thanks in advance!
