Hello Mumsnet! 
I recently made a trip that involved seven flights. On each flight, I had to endure violent films on other passengers' in-flight entertainment systems.
These films were clearly inappropriate for children. Yet they could been seen by children.
I wonder if we could campaign for airlines either to provide only Universal (U) rated films, or to design their screens so that only passenger sitting directly behind the screen has a clear picture.
Any ideas?
(PS I am not (yet!) a mother: when I am I know I would not want my children being exposed to violent or explicit films)
