There is confirmation that the $75 fee is an award processing fee for those who book over 21 days out and then voluntarily request the outbound leg(s) begin in fewer than 21 days. The fee will not apply to AAdvantage statusholders using miles from their own account, no changes in this last bit. The source verified; you can confirm as much on TB. The sky is not falling, the loophole has finally been properly stoppered.
