PAXboy - I read this off the CAA site, so maybe concerned PAX should go down the route you suggest, but I can't see it making any difference, if any
What is the policy for passengers who are drunk on board an aeroplane?
It is an offence to be drunk on board an aircraft, and passengers who behave in a threatening, abusive, insulting or disorderly manner towards a member of the crew, or intentionally interfere with their performance can be subject to a maximum penalty of an unlimited fine and/or two years’ imprisonment.
The CAA's principal concern is the overall safety of the flight, and our main role on this issue is as adviser to the Government. The Safety Regulation Group's Flight Operations Department is actively involved with the Department for Transport in monitoring the frequency and nature, together with analysis, of such occurrences in order to establish if any further legislative action may be necessary.
