As a counterpoint, the lunchtime flight in J/F (not Y/W) did allow for a relaxed late morning champagne breakfast in the LHR T4 F lounge (is that still there?), a nice lunch on board, and then a late afternoon snooze. After waking up, a movie and some Kath & Kim would see see you though to the second meal service. A shower at the refuelling stop, a few more drinks on board with a light meal, and I'd be dropping off again while trying to watch another movie, regardless of what was happening around me.

The evening arrival into Sydney allows a get-together with friends/loved ones before hopefullty a good night's sleep.

As the doc says, I would avoid these timings down the back, however.
