On March 27th 2009 I flew from Warsaw to Dublin by Aer Lingus and was seated in a window seat. As soon as this flight took off a group of very inebriated passengers made their way down to the vacant seats beside me. Three of them perched themselves facing rearwards on these two seats while the others mainly occupied the aisle. They then started openly drinking vodka from bottles. At one stage one man was so drunk that he fell off the seat he was kneeling on and knocked my coffee over me. Others in this group were using their mobile phones while at least one of them was smoking a cigarette. The cabin crew made very little effort to dissuade these people from their activities. It would have been very difficult for me to leave my seat at any stage during the flight and impossible to have worked on my laptop. I was so affected by the experience that I wrote to Aer Lingus and asked for their comments. That was six weeks ago and to date they have not bothered to respond to my letter.
