Well, if I understand the text on the mailer about conversion next year, THIS year, I get the day US Air club pass, $100 companion passes, and, I think, 10K anniversary miles. Afterwards, when then changeover takes place, yeah, I'm not sure what the new card will have.

I'm thinking of cancelling this US Air MCn months later thinking that I can then apply for the upcoming Barclay's AA MasterCard and get a bonus offer? Otherwise, the US Air Barclay's MasterCard will, I imagine, simply be replaced with no bonus miles, etc.
