I signed up for the AA Exec MC in June, and I'm working on the $10K spend via some work I'm doing on my house.

I recieved an offer for a 0%/$0 balance transfer card yesterday. If I do my $10K spend on the AA card, and then move it to the 0% card, will my $10K spend still qualify?

Also, I'm thinking of making part of my $10K spend a very expensive airline ticket that I may or may not need next spring. If I cancel the reservation, the funds would be returned to the AA card after the balance transfer goes through. How would that work? Would AA yank my bonus miles if the balance had already been cleared from the card?
