I had a recent flight on a regional arm of a major Australian airline with 2 seats a side. The man sitting next to me was both very large and grossly obese. His body wasn’t contained by the seating arms and spread out through them into the aisle and well into my seating space pushing me against the wall of the plane. His body was of such a shape that his head could not touch the headrest and so he fell asleep sitting forward in the seat , and in doing so his arm pushed right across my chest to the far side of my body and restricted my ability to breathe.
I woke him up to pull his arm back but 10 minutes later it happened again. when the drinks cart went past he had to turn sideways and compress hard into me to clear his body from the aisle. It was a short flight and all seats taken so I just put up with it. As soon as I got home I found a way to actually contact the airline by email on their system to ask about their policy and my rights. Over 3 weeks later I received acknowledgement of my email and a day after that a soothing letter that did not answer my question. Do others have similar experiences, has anyone got a response, and should there be a regulation. The reason I asked them is we have a series of overseas trips coming with the same major airline and this would just be impossible to live with on a flight to Europe.
