The following is a formal complaint to the CAA sent 26th May 2017. The message is - stop pandering to the needs of drunken louts and actively protect the welfare of the majority of well behaved passengers. When those louts comprimse passenger welfare and potentially flight safety actually do something about it and send a claear message that this behaviour will not be tollerated. "I wish to register a formal complaint with respect to flight EZY426 Edinburgh to Bristol 26-05-17. A group of at least 6 male passengers and principally the occupants of seats 21 A,B,C and 22 A,B,C were clearly intoxicated and disruptive before boarding this flight in Edinburgh. They were also abusive and disruptive throughout the flight. They made fun of and humiliated the female cabin crew throughout the safety briefing and made it difficult to understand what was being said. Whilst one member of the female cabin staff asked them to moderate their behaviour she was ignored and also subject to abuse which she ignored. Despite the fact that these passengers were clearly drunk, the flight attendants continued to serve them alcohol which made their behaviour worse. The female fight attendant asked us if we wanted to move seats midway through the flight but there was little point in trying to move my 79 year old mother and 83 year old father at this stage. No further attempt was made by the cabin staff to subdue the disruptive passengers. The Cabin Manager "Charlie" was conspicuous by his absence allowing the more junior female flight attendants to try to deal with the disruptive passengers. He made no attempt to deal with their behaviour directly and was clearly intimidated by their behaviour. Towards the end of the flight the Cabin Manager alerted to my concerns, asked my mother "what the problem was?" - a clear attempt to absolve himself of any responsibility and a wholly inappropriate way to deal with the situation. We continued to suffer abuse for the remainder of the flight with the underside of my seat being kicked deliberately and the passenger in seat 21A who was clearly drunk, pushed my arm from between the seats and became extremely abusive. Upon landing I reported the drunken and abusive behaviour to PC3403 Julian Cornwell of the Bristol Airport Police Unit and requested that he formally note the complaint. He noted that the ground staff at Edinburgh Airport should have prevented the disruptive passengers from boarding and that it would have been within the gift of the flight crew to have requested that the offending passengers be detained upon arrival. He also noted that the police were impotent in dealing with this sort of behaviour and that "no EasyJet flights would leave the airport if he had to arrest all of their drunk passengers at boarding". The behaviour of the EasyJet flight attendants and the Cabin Manager in particular were clearly tolerant of and did nothing to prevent the disruptive offensive and abusive behaviour of a group of young male passengers. They were clearly intimidated by the behaviour of these individuals and continued to serve them alcohol. I will be copying this complaint to EasyJet and the Airport Police at Edinburgh Airport. This sort of behaviour has the potential to compromise flight safety and passengers should not be subject to this sort abuse. Can I be assured that the CAA will take this matter seriously and perhaps request a review of protocols which allow intoxicated and disruptive passengers to board aircraft? Further, can I be assured that ground staff and appropriate officials at Edinburgh Airport will receive formal correspondence on this matter?"
