Confirming the low priority of FF ticket holders, I have been on two FF trips where earlier flights were cancelled, so the flight was overbooked, and the FA's have tried to put us off of the plane and let other passengers (WHO THEY HAD ALREADY REBOOKED WITH OUR SEATS ON THEIR BOARDING PASSES) take our seats. In both instances, I had my wife and 2 kids (who were small at the time) with us, so we had boarded early (when the airlines still let you do that with kids. I refused to give up our seats, since we were already in them, and had made the reservations 9 months in advance. In both cases the passengers they tried to put in our seats made the FAs back off, and agreed to go elsewhere, but it just confirms that you are the lowest priority if you are flying on FF tickets.
