I love my Chase United MP Select Visa. Great perks. The thing was, I only got 30K miles, and when I later convinced my girlfriend to get one, they were running a 50K offer. Only slightly peeved (I'm not one to complain when it really isn't anyone's fault) I decided to at least ask Chase if they'd give me the extra 20K even though I got my card over 6 months ago. And lo and behold, I get an answer within 24 hours saying, "Yes, of course!" with the miles posting the next day. Since Chase operates a whole slew of other cards, this would probably work for you, too. I suggest you check what offer you got and what they've offered other people in the last few months. I love my card, and now I love Chase, too.
