Great thinking in setting up this thread WineCountry!

It may also make sense to know a few more things:

• Did the person being denied show their (now expired) physical UA Elite card?
• What airline you were flying (i.e. your UA card won't be helpful getting you into a LH lounge if you're flying AS)
• Itinerary (at least high level like USA -> USA) to determine if denial was due to intricacies of *Lounge Access Policy or the actual freakin' card
• Status level of Traveller (i.e. UA Gold, UA Platinum, UA 1K, GS, etc.)
• If you showed the UA Virtual Card was it up to date and did it display the *Gold logo on it?

If this thread unfortunately becomes popular, I may create a spreadsheet to track the issues. It may also be useful reporting the successes as well since I hear the LH Group is very finicky with admission and knowing their reasoning why you got in can be helpful for those fighting to get in in the first place. It may also be useful to track how often you were challenged to produce a card (virtual or otherwise). I'll leave it up to the fine tastes of the OP to determine what's the best approach to tracking these issues (and successes)

When I spoke to UA early this in January about the lack of physical card, the agents I spoke to told me specifically that UA has an agreement with the various lounge operators now in effect that the mere presentation of the virtual card along with your boarding pass on a * flight should grant you access to the relevant * lounges. If you receive pushback from the lounge operators, remind them of the agreement (and get a supervisor involved if need be).

Safe Travels,
