I have never seen air-rage except for the incident that was caught on video of the NRT bound 747 that had to land in Alaska. However, on a flight from SFO-ORD last year, one PAX was offended and belittled by an FA after he simply asked a question regarding an FAA delay. The FA turned around and commented that "the 80 year old man should be able to take better care of himself". Everyone around her (including myself) knew that this comment was directed at the passenger who looked to be somewhat younger. His wife proceeded to make a statement to that FA, and then the man made his statement. I turned around and told the FA that I heard the comment, and thought she should apologize. The passenger's question was legitimate, and he was actually quite on top of things, so there was no reason for the comment. The rest of the passengers (including another younger FA who heard the comment) was quite surprised that one could be that low.
