I'm 99% sure I know the answer, but giving the advice to a friend so want to triple check: For a partner award, there is no 'x hours before departure' cancellation requirement other than before they would be marked as a no-show? So they would be marked as a no-show if not checked in on time or if not boarded on time, but United doesn't have any policy beyond "cancel before marked as a no-show" for partner awards, correct?
