Alternatively
Why not just create a "quiet flight". We have quiet cabins on some trains and I think it is a great idea.
No Apple earbuds which appear to let out as much noise as they put in.
No babies because we know in advance that they dont really like Air Pressure differences.
No children that don't know how to shut the fuck up or spoiled brats that think banging their feet against the back of your seat is Ok....And no parents that let them do this shit.....
No business men, loudly havering on about how wonderfull they are or how much they apparently earned on their last deal, strange because they are travelling in economy class....
No one using their mobile phone up until the last three seconds before take off, they only use them to inform people that they are in a plane. These people have a severe infériority complex.
No one wandering up and down the aisle to see their friends, who don't really want to be visited....
No one pestering you to buy perfume, watches, gadgets, lottery or raffle tickets, or requesting spare change for charities..
Now that would be a civilised way to travel...
