Yeah, I was tossed out of business class once for a FAM at the last minute (my wife determined that he was a FAM after sitting next to him for hours and observing his behavior-I was given no reason for the downgrade). I got downgrade compensation but was in coach, and separated from my wife for 12+ hours, so I wasn't happy. In addition, I've been bumped out of domestic F so a security guard for a politician could have my seat. I've also been downgraded out of NH First to Business once for some VIP.
Things happen. Roll with the punches.
