@QRC3288 - right, I see what you mean, I had never thought through things so carefully. I think that the 77G is probably despised by the PE passnegers too, I certainly prefer the 77H, as long as I get a seat on the the toilet side of the cabin!

Going back to the Y passengers using the PE toilet issue, I have never seen this, but of course anything can happen. Is it the case that passengers sitting right up front in Y are more likely to have status and are therfore more likely to be aware of the "rules" about toilet use ?
