I was seated next to a FAM in first class on a recent flight and he was really gross almost the entire flight.

Shortly after take-off, he got a pinch of smokeless tobacco out of his "little black bag", put it in his mouth and proceeded to spit every few minutes into his empty water bottle, for the rest of the flight. Needless to say, it was very difficult to sit next to him and impossible to eat my meal, which I wanted to, since I was connecting to an international flight.

Anyone know if there are any regs or policies for FAMs while they are traveling that would cover this type of behavior?
