The issue with only one meal on overnight flights is not the volume of food as far as I am concerned, its just that one may choose the breakfast but have to put up with the clatter of others eating supper and vice versa which really defeats the argument of extra sleep time. Not being even offered a cup of tea / coffee in the morning is appalling. I wonder ? Do econ class pax get 2 meals ? or just a choice of one or the other ?
