"This offer is available to CitiŽ/AAdvantageŽ cardmembers who receive this communication."
"Offer may be modified or withdrawn at any time without notice, is not transferable, and cannot be combined with any other offer."
Those two sentences are very important. I'm sure some FT'ers will take the plunge despite not having received this offer so we will eventually find out whether or not they are enforcing their rules...but it would appear it is targeted.
Then again, the previous offer for 20K AA miles also contained these clauses as far as I can remember and I still applied and (in theory) will receive miles despite not having been targeted.
YMMV per usual
