FWIW my wife and I both have the old United card, we got them about 7 months ago.

I couldn't get the 60,000 offer to appear so I used the link provided in this thread - first for me, then after receiving instant approval I waited until I received my card then I submitted a request for her, which was also instantly approved. I have two other recent Chase cards.

When I set up my card I had them change the statement day to 1 Feb (as soon as I could get it) and made two quick purchases.

My 50,000 miles posted today! I expect we'll get my wife's card this week but we did get the email saying she would get 50,000 miles with the first purchase - I didn't get that.
