Those recorded delays amount to 1 every night during that period. So if I had moved to under the flight path and read the agreement I might have put up with the noise during the day as growth is restricted. Also I would have said to myself that only flights after 9.30 in 'exceptional circumstances', but every night!.
Airlines who operate from there know the game plan and do so at their own risk/cost. Good to see that this issue is being looked into.
