Paul, I agree. You read it better than I did. One can book a reservation, have it put on a courteousy hold, then come back and ticket it using Aviator miles.
But one cant use their Aviator miles to do this when they have sufficient miles in the AAdvantage account to cover the award.
If one cancells an award ticket using Aviator miles, the miles will not return to Aviator, but the member would be subject to the reinstatement fees.
