Beano, we were in PE on the A380 from Melbourne to Dubai and in Y from Dubai to Lisbon on the 777, same on return. The three PE bathrooms on the A380 are in the nose at the front of the PE cabin and were plenty for the PE passengers apart from the fact that the free or occupied lighting system didn't work well. I haven't kept up to date on the Emirates program for introducing PE on their 777's so don't know how that is progressing. As mentioned in my earlier post we could not book PE on Emirates using the QF site; I assume that has not changed. So, we did miss out on QF points and SC but life is too short to worry about that!
