Just a quick tip for those with a Citi Executive card. When you add authorized users, they get access to Admirals Clubs. However, those authorized users do not need to activate the card in order to access the club. This may give you some peace of mind giving out authorized user cards.

I contribute to a friend’s annual fee and he makes me an authorized user. When I got the card, I peeled off the sticker and didn’t call/register. The card works for admission. Obviously I can’t charge on it.
