We've just returned from KUL with MH in J. Aircraft was an A380. We were in the middle seats with an occupant of the adjacent window and aisle seat to himself. He set the window seat up as a bed and used the aisle as his seat. He went to sleep after a couple of hours. He was, without doubt, one of the noisiest snorers it was possible to come across. We could hear it through the headphones whilst watching films and also through earplugs plus a pair of headphones when we tried to sleep. My wife eventually tried 3 times to wake him up to no avail. I eventually shook him and woke him and stated the issue to which he acknowledged the problem and he, fortunately, stayed awake for the last 3 hours of the flight. The CC just apologised but refused to take any action. It prevented either of us getting any meaningful sleep on the 13hour flight.

What would you have done? Was I out of order?
