My guest and I were both at the counter with our LH BPs (MUC-TLS). I just made Gold but don't have the physical card yet, tried the printout on the CO site but she said no. So I busted out the PC membership card. She looked at it kind of funny, consulted her paper reference sheet, and then scanned the card. She was surprised when I said I could be admitted but she insisted that I could not bring my guest in. I got the impression that LH doesn't deal much with the paid membership cards and the rules associated with them. Both the lounge agent and the customer service agent down the terminal kept telling me if I was gold (they can't see CO's updated records) I could bring a guest in. Whatever.
My next attempt will be on Friday in FRA. I plan to print out the pages from the *A website and highlight the criteria I meet.
Thx for the responses.
