From the people that put their elbows in your ribs, to the loud groups, kids that do not stop screaming, people that manage to spill their coke on your knees, people that are scared to death(poor guys) and get sick, no flight is ever quiet. The only flights I like are transcontinentals where there is more room between seats.
One receipt: great noise cancelling earphones and one sleeping pill. When you land ready to work or party.
Last thursday in the flight Munich Barcelona one guy which language was not to be understood, stood up in the middle of the flight and said :"jump, jump".
At the request of the stewardess(scared) we, (my two colleagues and myself) were asked to control him, the spanish guardia civil took over after landing. no one got more infos.
I hate to fly..
Cheers
