I did this route with QF J on the way back after Xmas. Completely agree on the topper, great addition and very simple. As an aside, I thought the service was a world ahead of BA. I've done a lot of BA CW and 1x BA F. I thought QF J beat CW hands down and in fact thought it also beat BA F, although 1 sector isn't a truly fair comparison. Plus the pyjamas etc, made it feel more F than J.
