I don't think he was asking about the lounge club which has a separate card and you must be there, though it makes it free for you and a guest. I think he is asking about a upgrade on a Ritz room since the card comes with 3 certs...Im unsure, but if you are booking it for them and apply the cert at booking, I Don't see why not.

I used $200 on Southwest giftcard, since I know my wife will be getting the companion pass this year. no problem getting credit. I will probably order another as soon as she actually gets the pass.
