I have a hard time believing the people who booed knew the family was escorting a fallen soldier home. It seems like the airline could have explained that better. I can understand people being frustrated about possibly missing connections if all they were told was "a special military family". That could mean a thousand things, and being veterans doesn't mean we're owed special treatment everywhere. I think the crew, or the father, after the boos, should have come up on the intercom and said something to the effect of, "We are escorting our son's body home after he was killed serving overseas. Thank you for your patience and understanding, and we apologize for any inconvenience." I bet the people who booed would have felt like absolute shit, and the subtle point was the one to make here.
