To answer the OP, I received the 20,000 enrollment bonus today and also an email this morning with the 6,000 discount as described by the others.

For some reason I'm not finding out where to go to arrange to pay my credit card bill online. I have temporarily misplaced the paperwork that came with my new card. Could someone email me with the URL?

A second stupid question--if I use the feature where I can get $100 off my ticket, do I lose the ability to earn miles on those tickets?
