Thanks for the question. Yes, UC membership card, not UA MP (elite status) card. Is need the only reason for obtaining such a card? I don't need a card, perhaps I simply desire it.

I’m the person who early in this thread wrote “I don’t believe there are physical hard-copy-plastic UA Club membership cards anymore.” I was subsequently quoted and corrected. I simply wanted to see if and how I could receive a card.

Might it be needed if a club member was traveling on a Star Alliance or a contracted partner operated flight using a frequent flyer number other than one’s UA MP number and forgot/lost their phone? Also kinda like a Global Entry physical card. AFAIK other than returning from Canada to the US by air a physical GE card is not needed … but many still desire a physical GE card, if nothing else as proof of GE status.

FWIW, other than the one call, I have not lost and do not intend to lose any sleep over this concern. I’m a happy camper as long as I can get into a club when I think I should be able to.
