My husband who has autism stood seconds before the seatbelt sign went off as the steps were being attached. The staff were slow to turn them off. Being in the first seats and despite most of the cabin standing, a female crew member with a shaved head put her hands on my husband and guided him back into his seat. He asked her not to manhandle him. I said he has autism. He sat down but immediately a dramatic lad (apparent Cabin Manager) came over, lent in my husbands face and started to shout at him. This to the point when I pushed my magazine between their faces and told the crew member to stop escalating, behave professionally and back off. My husband remained seated and did not respond. The staff member had him trapped in his seat with his face almost touching my husbands. I repeated over and over that my husband had autism. I asked for the cabin managers name. He refused to give it and told me to get off his plane. At no point did I raise my voice or behave in an aggressive manner. However the manager started asking if I could read and held out his shirt in an exaggerated way while telling me to read the badge over and over. I explained that I didn’t have my glasses on and his behaviour was holding us up from leaving. He eventually said his name was Tom, mocked me for wanting to complain and abused me as I quietly left the cabin. It was an absolutely disgraceful display of professionalism, intolerance and inappropriate misuse of power. This crew had no understanding of Autism and were determined to humiliate us. I got off the flight very upset, dreading my return journey and wrote a complaint there and then. I was told it would be investigated. Easy Jet first sent me a reply destined for another customer which was absolutely nothing to do with my complaint. They then sent me a reply where they said that I (in place of my husband) had stood up and repeated a swathe of lies clearly given to them by these two crew. Certainly not an investigation. I had thought that the two crew member would lie for each other as they were smug about me making a complaint had no respect and acted with impunity. However, I gave Easy Jet more credit than they deserved in believing they would investigate. Easy Jet staff lack any understanding around Autism. Their cabin manager was dramatic, aggressive and abusive to a seated passenger. My husband is a director of a large organisation that regularly books easy Jet to fly their staff. This is something he no longer feels he can do as he has seen their behaviour first hand. In forty years and travelling all around the world on BA, I have never seen or experienced such poor communication or behaviour.
