US Airways card, opened on 5/10/13 (so annual fee was scheduled to post on this coming billing cycle). Called in, specifically said "I like earning Dividend Miles, but given that I have status with US Airways and get most of the perks through that, I'm not sure if it's worth the annual fee". Rep immediately waived it, all in all a painless process.

$15.7K spend so far this year, all MS (about $17K total since getting the card -- spent a bit on it right after getting the card, zero charges from August - February, will MS up to $25K total for the 10K PQMs then send it right back to the sock drawer).
