The title on the thread says 'UA VISA Promotion' but the wording of the offer says one must use 'a Visa Signature' card. So it's not just the United Visa Card... unless the rules they printed are wrong.
I don't fly UA that often anymore, but still have a good amount of miles. This could be so good for getting E+ on an award trip to Australia!

Looks like the offer is targeted. Oh well. Not expecting anything out of this, but what really gets me is that I canceled my UA Chase Visa on Dec 31st because I was sick of the annual fee. The targeted offer looks like it was mailed out in early December, and I would have kept the card if they had sent it to me. Just less business for UA and Chase because of that....
