Sounds like the sort of drink-fuelled anti-social behaviour that bedevils public spaces throughout the UK. It seems to be a peculiarly British problem - comparatively few people from other European countries go out with the specific intention of getting p*ssed (to use the local vernacular). Transport operators (not just airlines but train operators too) should take a much tougher line, and be given due backing by police and the courts. 'Just having a good time' doesn't cut it, as excuses go.
