Thanks again, everyone. I really appreciate everyone's ideas and expertise! This is a real time-saver for us as we search for the next credit card.

We're still thinking the United Explorer because United has the most flights out of Chicago and we have the most points on United. We still do fly American, though I'm thinking that once we get this card, we'll try to stay focused and use United for almost all flights, assuming they fly to where we're going.

Thank you again. If anyone has any special tips I should know about getting this card and special offers, those are certainly welcomed. In the meantime, though, this board has been a wealth of information.
