Hello all - adding on to this old thread. I will be travelling LH from DTW-FRA later this week. I am a 1P with United but havent received my card in the mail yet, so am wondering whether any of you has had any luck with using the lounge without having your 1P/*G card on you? On reading other threads, I am planning to take a printout of my MP summary page that shows that I am a Prem Exec - anything else I need to keep in hand?

Thanks!
