On an economy flight Sydney to WA some time ago I had to sit next to a female passenger that was 6 parts to the wind when she boarded. Her male colleague was trying to disown her as she became merrier during the flight drinking white and red wine!! They were returning to Perth after a workshop in Sydney....the name of her Company (a large one at that)was clear for all to see on the lapel name tag! It was all quite innocent to begin with as she quietly sang along to the songs being pumped into her cranium from her earphones. At dinner, It became a little comical as she tried to coordinate putting food in her face and singing at the same time. Not a pretty sight. The singing became louder as her requests for more wine were fulfilled by the airline, to make matters worse, she was singing out of tune and attracting the attention of other passengers. Male colleague had buried his face in a pillow against the window and was feigning sleep! It was suggested to him to take control of his colleague or face the consequences of his Company being made aware of this escapade. Colleague intervened, asking her to be quiet and not really knowing what to do. After some time she threw her arms around him and drifted off to a slumber. Every now and then she would awake, blurt out some lines from a song and go back to counting fairies. About 90 minutes out from Perth she woke up and started to get abusive toward me and her colleague whilst she continued to drink. C'est la vie!!
On many business class flights to Asia, I witnessed huge consumption of alcohol by many 'business men' (for the record I am an Aussie bloke). From the moment they boarded the plane and sat down they were into the grog, right through dinner/breakfast/lunch and the duration of the flight or until they fell asleep i.e. passed out. To the Northern Hemisphere particularly on the 380's many of them camped at the bar and drank for the duration of the trip. On the trip to Perth, into Asia and the Northern Hemisphere, I never witnessed any attempt by the airlines to curtail alcohol consumption. In business class I witnessed passengers becoming rude, abusive and unpleasant. It is not in the interests of the airline to advertise restricted alcohol on their flights. Revenue would suffer enormously. Airline staff face the unpleasant task of telling drunkards 'no more'...which in many cases only fuels the fire. The bogans will never go away, but it isn't restricted to bogans on cheap airlines...there are slobs in business class too, travelling as representatives of their companies and getting skunk drunk. Airline staff have to take responsibility for saying 'no more'....and their airline has to support them.
A problem that is not going away. Having to sit next to a passenger singing out of tune whilst drunk is a real pain the rear end too!!
